supports Donut, Pie and Line styles. See setBarStyle() for more details. * * ### Colors * Generally QRoundProgressBar uses its palette and font attributes to define how it will look. * * The following \a QPalette members are considered: * - *QPalette::Window* background of the whole widget (normally should be set to Qt::NoBrush) * - *QPalette::Base* background of the non-filled progress bar area (should be set to Qt::NoBrush to make it transparent) * - *QPalette::AlternateBase* background of the central circle where the text is shown (for \a Donut style) * - *QPalette::Shadow* foreground of the non-filled progress bar area (i.e. border color) * - *QPalette::Highlight* background of the filled progress bar area * - *QPalette::Text* color of the text shown in the center * * Create a \a QPalette with given attributes and apply it via `setPalette()`. * * ### Color gradient * \a Donut and \a Pie styles allow to use color gradient for currernt value area instead of plain brush fill. * See setDataColors() for more details. * * ### Value text * Value text is generally drawn inside the QRoundProgressBar using its `font()` and \a QPalette::Text role from its `palette()`. * * To define pattern of the text, use setFormat() function (see Qt's \a QProgressBar for more details). * * To define number of decimals to be shown, use setDecimals() function. * * ### Font * To use own font for value text, apply it via `setFont()`. * * By default, font size will be adjusted automatically to fit the inner circle of the widget. */ class THIRDPARTY_EXPORT QRoundProgressBar : public QWidget { Q_OBJECT public: explicit QRoundProgressBar(QWidget *parent = 0); static const int PositionLeft = 180; static const int PositionTop = 90; static const int PositionRight = 0; static const int PositionBottom = -90; /** * @brief Return position (in degrees) of minimum value. * \sa setNullPosition */ double nullPosition() const { return m_nullPosition; } /** * @brief Defines position of minimum value. * @param position position on the circle (in degrees) of minimum value * \sa nullPosition */ void setNullPosition(double position); /** * @brief The BarStyle enum defines general look of the progress bar. */ enum BarStyle { /// Donut style (filled torus around the text) StyleDonut, /// Pie style (filled pie segment with the text in center) StylePie, /// Line style (thin round line around the text) StyleLine }; /** * @brief Sets visual style of the widget. * \sa barStyle */ void setBarStyle(BarStyle style); /** * @brief Returns current progree bar style. * \sa setBarStyle */ BarStyle barStyle() const { return m_barStyle; } /** * @brief Sets width of the outline circle pen. * @param penWidth width of the outline circle pen (in pixels) */ void setOutlinePenWidth(double penWidth); /** * @brief Returns width of the outline circle pen. */ double outlinePenWidth() const { return m_outlinePenWidth; } /** * @brief Sets width of the data circle pen. * @param penWidth width of the data circle pen (in pixels) */ void setDataPenWidth(double penWidth); /** * @brief Returns width of the data circle pen. */ double dataPenWidth() const { return m_dataPenWidth; } /** * @brief Sets colors of the visible data and makes gradient brush from them. * Gradient colors can be set for \a Donut and \a Pie styles (see setBarStyle() function). * * *Warning*: this function will override widget's `palette()` to set dynamically created gradient brush. * * @param stopPoints List of colors (should have at least 2 values, see Qt's \a QGradientStops for more details). * Color value at point 0 corresponds to the minimum() value, while color value at point 1 * corresponds to the maximum().

Users can invoke the color picker by clicking on it, or by navigating to it and pressing Space. They can use the mouse or arrow keys to navigate between colors on the grid, and select a color by clicking or by pressing Enter or Space. The colorChanged() signal is emitted whenever the color picker's color changes. The widget also supports negative selection: Users can click and hold the mouse button on the QtColorPicker widget, then move the mouse over the color grid and release the mouse button over the color they wish to select. The color grid shows a customized selection of colors. An optional ellipsis "..." button (signifying "more") can be added at the bottom of the grid; if the user presses this, a QColorDialog pops up and lets them choose any color they like. This button is made available by using setColorDialogEnabled(). When a color is selected, the QtColorPicker widget shows the color and its name. If the name cannot be determined, the translatable name "Custom" is used. The QtColorPicker object is optionally initialized with the number of columns in the color grid. Colors are then added left to right, top to bottom using insertColor(). If the number of columns is not set, QtColorPicker calculates the number of columns and rows that will make the grid as square as possible. \code DrawWidget::DrawWidget(QWidget *parent, const char *name) { QtColorPicker *picker = new QtColorPicker(this); picker->insertColor(red, "Red")); picker->insertColor(QColor("green"), "Green")); picker->insertColor(QColor(0, 0, 255), "Blue")); picker->insertColor(white); connect(colors, SIGNAL(colorChanged(const QColor &)), SLOT(setCurrentColor(const QColor &))); } \endcode An alternative to adding colors manually is to initialize the grid with QColorDialog's standard colors using setStandardColors(). QtColorPicker also provides a the static function getColor(), which pops up the grid of standard colors at any given point. \img colorpicker1.png \img colorpicker2.png \sa QColorDialog */ /*! \fn QtColorPicker::colorChanged(const QColor &color) This signal is emitted when the QtColorPicker's color is changed. \a color is the new color.

In plottables like QCPGraph it is used to store how scatter points shall be drawn. For example, \ref QCPGraph::setScatterStyle takes a QCPScatterStyle instance. A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can be controlled with \ref setSize. \section QCPScatterStyle-defining Specifying a scatter style You can set all these configurations either by calling the respective functions on an instance: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1 Or you can use one of the various constructors that take different parameter combinations, making it easy to specify a scatter style in a single call, like so: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2 \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref isPenDefined will return false. It leads to scatter points that inherit the pen from the plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes it very convenient to set up typical scatter settings: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size) constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref ScatterShape, where actually a QCPScatterStyle is expected. \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points. For custom shapes, you can provide a QPainterPath with the desired shape to the \ref setCustomPath function or call the constructor that takes a painter path. The scatter shape will automatically be set to \ref ssCustom. For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap. Note that \ref setSize does not influence the appearance of the pixmap. */ /* start documentation of inline functions */ /*! \fn bool QCPScatterStyle::isNone() const Returns whether the scatter shape is \ref ssNone. \see setShape */ /*! \fn bool QCPScatterStyle::isPenDefined() const Returns whether a pen has been defined for this scatter style.

It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer, QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers bottom to top and successively draws the layerables of the layers. A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base class from which almost all visible objects derive, like axes, grids, graphs, items, etc. Initially, QCustomPlot has five layers: "background", "grid", "main", "axes" and "legend" (in that order). The top two layers "axes" and "legend" contain the default axes and legend, so they will be drawn on top. In the middle, there is the "main" layer. It is initially empty and set as the current layer (see QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of course, the layer affiliation of the individual objects can be changed as required (\ref QCPLayerable::setLayer). Controlling the ordering of objects is easy: Create a new layer in the position you want it to be, e.g. above "main", with QCustomPlot::addLayer. Then set the current layer with QCustomPlot::setCurrentLayer to that new layer and finally create the objects normally. They will be placed on the new layer automatically, due to the current layer setting. Alternatively you could have also ignored the current layer setting and just moved the objects with QCPLayerable::setLayer to the desired layer after creating them. It is also possible to move whole layers. For example, If you want the grid to be shown in front of all plottables/items on the "main" layer, just move it above "main" with QCustomPlot::moveLayer. The rendering order within one layer is simply by order of creation or insertion. The item created last (or added last to the layer), is drawn on top of all other objects on that layer. When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below the deleted layer, see QCustomPlot::removeLayer. */ /* start documentation of inline functions */ /*! \fn QList QCPLayer::children() const Returns a list of all layerables on this layer. The order corresponds to the rendering order: layerables with higher indices are drawn above layerables with lower indices. */ /*! \fn int QCPLayer::index() const Returns the index this layer has in the QCustomPlot.

If the layerable has multiple entities whose antialiasing setting may be specified individually, this function should set the antialiasing state of the most prominent entity. In this case however, the \ref draw function usually calls the specialized versions of this function before drawing each entity, effectively overriding the setting of the default antialiasing hint. First example: QCPGraph has multiple entities that have an antialiasing setting: The graph line, fills, scatters and error bars. Those can be configured via QCPGraph::setAntialiased, QCPGraph::setAntialiasedFill, QCPGraph::setAntialiasedScatters etc. Consequently, there isn't only the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw calls the respective specialized applyAntialiasingHint function. Second example: QCPItemLine consists only of a line so there is only one antialiasing setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the respective layerable subclass.) Consequently it only has the normal QCPItemLine::applyDefaultAntialiasingHint.

This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses. A Layout element is a rectangular object which can be placed in layouts. It has an outer rect (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference between outer and inner rect is called its margin. The margin can either be set to automatic or manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic, the layout element subclass will control the value itself (via \ref calculateAutoMargin). Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested. Thus in QCustomPlot one can divide layout elements into two categories: The ones that are invisible by themselves, because they don't draw anything.

In most cases, layouts don't draw anything themselves (but there are exceptions to this, e.g. QCPLegend). QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts. QCPLayout introduces a common interface for accessing and manipulating the child elements. Those functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions to this interface which are more specialized to the form of the layout. For example, \ref QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid more conveniently. Since this is an abstract base class, you can't instantiate it directly. Rather use one of its subclasses like QCPLayoutGrid or QCPLayoutInset.

This \a formatCode is an extended version of the format code used e.g. by QString::number() and QLocale::toString(). For reference about that, see the "Argument Formats" section in the detailed description of the QString class. \a formatCode is a string of one, two or three characters. The first character is identical to the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed format, 'g'/'G' scientific or fixed, whichever is shorter. The second and third characters are optional and specific to QCustomPlot:\n If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g. "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5 [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot. If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the cross and 183 (0xB7) for the dot.

To only display the decimal power, set the number precision to zero with \ref setNumberPrecision. Examples for \a formatCode: \li \c g normal format code behaviour.

These are the pure virtual functions, you must implement: \li \ref clearData \li \ref selectTest \li \ref draw \li \ref drawLegendIcon \li \ref getKeyRange \li \ref getValueRange See the documentation of those functions for what they need to do. For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot coordinates to pixel coordinates. This function is quite convenient, because it takes the orientation of the key and value axes into account for you (x and y are swapped when the key axis is vertical and the value axis horizontal). If you are worried about performance (i.e. you need to translate many points in a loop like QCPGraph), you can directly use \ref QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis yourself. Here are some important members you inherit from QCPAbstractPlottable:
QCustomPlot *\b mParentPlot A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.
QString \b mName The name of the plottable.
QPen \b mPen The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable (e.g QCPGraph uses this pen for its graph lines and scatters)
QPen \b mSelectedPen The generic pen that should be used when the plottable is selected (hint: \ref mainPen gives you the right pen, depending on selection state).
QBrush \b mBrush The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable (e.g. QCPGraph uses this brush to control filling under the graph)
QBrush \b mSelectedBrush The generic brush that should be used when the plottable is selected (hint: \ref mainBrush gives you the right brush, depending on selection state).
QPointer\b mKeyAxis, \b mValueAxis The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of the axes is null, don't draw the plottable.
bool \b mSelected indicates whether the plottable is selected or not.

For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight. Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the QCPItemRect. This way the start of the line will now always follow the respective anchor location on the rect item.

Every item has at least one public QCPItemPosition member pointer which provides ways to position the item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two: \a topLeft and \a bottomRight. QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y direction, while following a plot coordinate in the X direction. A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords) are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0) means directly ontop of the parent anchor. For example, You could attach the \a start position of a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line always be centered under the text label, no matter where the text is moved to. For more advanced plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B in Y. Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent anchor for other positions. To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPoint.

In QCustomPlot, items are supplemental graphical elements that are neither plottables (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each specific item has at least one QCPItemPosition member which controls the positioning. Some items are defined by more than one coordinate and thus have two or more QCPItemPosition members (For example, QCPItemRect has \a topLeft and \a bottomRight). This abstract base class defines a very basic interface like visibility and clipping. Since this class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to create new items. The built-in items are:
QCPItemLineA line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).
QCPItemStraightLineA straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.
QCPItemCurveA curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).
QCPItemRectA rectangle
QCPItemEllipseAn ellipse
QCPItemPixmapAn arbitrary pixmap
QCPItemTextA text label
QCPItemBracketA bracket which may be used to reference/highlight certain parts in the plot.
QCPItemTracerAn item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.
\section items-clipping Clipping Items are by default clipped to the main axis rect (they are only visible inside the axis rect). To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect "setClipToAxisRect(false)". On the other hand if you want the item to be clipped to a different axis rect, specify it via \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and in principle is independent of the coordinate axes the item might be tied to via its position members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping also contains the axes used for the item positions. \section items-using Using items First you instantiate the item you want to use and add it to the plot: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1 by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just set the plot coordinates where the line should start/end: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2 If we don't want the line to be positioned in plot coordinates but a different coordinate system, e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3 Then we can set the coordinates, this time in pixels: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4 and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5 For more advanced plots, it is even possible to set different types and parent anchors per X/Y coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition. \section items-subclassing Creating own items To create an own item, you implement a subclass of QCPAbstractItem. These are the pure virtual functions, you must implement: \li \ref selectTest \li \ref draw See the documentation of those functions for what they need to do. \subsection items-positioning Allowing the item to be positioned As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add a public member of type QCPItemPosition like so: \code QCPItemPosition * const myPosition;\endcode the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition instance it points to, can be modified, of course). The initialization of this pointer is made easy with the \ref createPosition function. Just assign the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition takes a string which is the name of the position, typically this is identical to the variable name. For example, the constructor of QCPItemExample could look like this: \code QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) : QCPAbstractItem(parentPlot), myPosition(createPosition("myPosition")) { // other constructor code } \endcode \subsection items-drawing The draw function To give your item a visual representation, reimplement the \ref draw function and use the passed QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the position member(s) via \ref QCPItemPosition::pixelPoint. To optimize performance you should calculate a bounding rect first (don't forget to take the pen width into account), check whether it intersects the \ref clipRect, and only draw the item at all if this is the case. \subsection items-selection The selectTest function Your implementation of the \ref selectTest function may use the helpers \ref distSqrToLine and \ref rectSelectTest. With these, the implementation of the selection test becomes significantly simpler for most items. See the documentation of \ref selectTest for what the function parameters mean and what the function should return. \subsection anchors Providing anchors Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public member, e.g. \code QCPItemAnchor * const bottom;\endcode and create it in the constructor with the \ref createAnchor function, assigning it a name and an anchor id (an integer enumerating all anchors on the item, you may create an own enum for this). Since anchors can be placed anywhere, relative to the item's position(s), your item needs to provide the position of every anchor with the reimplementation of the \ref anchorPixelPoint(int anchorId) function. In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel position when anything attached to the anchor needs to know the coordinates. */ /* start of documentation of inline functions */ /*! \fn QList QCPAbstractItem::positions() const Returns all positions of the item in a list. \see anchors, position */ /*! \fn QList QCPAbstractItem::anchors() const Returns all anchors of the item in a list.

To find out whether a specific plottable is selected, call QCPAbstractPlottable::selected(). To retrieve a list of all currently selected plottables, call \ref selectedPlottables.

This class represents an axis rect, a rectangular area that is bounded on all sides with an arbitrary number of axes. Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the layout system allows to have multiple axis rects, e.g. arranged in a grid layout (QCustomPlot::plotLayout). By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index. If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref addAxes. To remove an axis, use \ref removeAxis. The axis rect layerable itself only draws a background pixmap or color, if specified (\ref setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be placed on other layers, independently of the axis rect. Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref insetLayout and can be used to have other layout elements (or even other layouts with multiple elements) hovering inside the axis rect. If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref QCP::iRangeZoom. \image html AxisRectSpacingOverview.png

It is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps". \image html QCPColorScale.png The color scale can be either horizontal or vertical, as shown in the image above. The orientation and the side where the numbers appear is controlled with \ref setType. Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are connected, they share their gradient, data range and data scale type (\ref setGradient, \ref setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color scale, to make them all synchronize these properties. To have finer control over the number display and axis behaviour, you can directly access the \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if you want to change the number of automatically generated ticks, call \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-autotickcount Placing a color scale next to the main axis rect works like with any other layout element: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation In this case we have placed it to the right of the default axis rect, so it wasn't necessary to call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color scale can be set with \ref setLabel. For optimum appearance (like in the image above), it may be desirable to line up the axis rect and the borders of the color scale. Use a \ref QCPMarginGroup to achieve this: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup Color scales are initialized with a non-zero minimum top and bottom margin (\ref setMinimumMargins), because vertical color scales are most common and the minimum top/bottom margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you might want to also change the minimum margins accordingly, e.g. setMinimumMargins(QMargins(6, 0, 6, 0)). */ /* start documentation of inline functions */ /*! \fn QCPAxis *QCPColorScale::axis() const Returns the internal \ref QCPAxis instance of this color scale. You can access it to alter the appearance and behaviour of the axis. \ref QCPColorScale duplicates some properties in its interface for convenience. Those are \ref setDataRange (\ref QCPAxis::setRange), \ref setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref QCPAxis::setLabel). As they each are connected, it does not matter whether you use the method on the QCPColorScale or on its QCPAxis.

So leaving adaptive sampling enabled has no disadvantage in almost all cases. \image html adaptive-sampling-line.png "A line plot of 500,000 points without and with adaptive sampling" As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are reproduced reliably, as well as the overall shape of the data set. The replot time reduces dramatically though. This allows QCustomPlot to display large amounts of data in realtime. \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling" Care must be taken when using high-density scatter plots in combination with adaptive sampling. The adaptive sampling algorithm treats scatter plots more carefully than line plots which still gives a significant reduction of replot times, but not quite as much as for line plots. This is because scatter plots inherently need more data points to be preserved in order to still resemble the original, non-adaptive-sampling plot. As shown above, the results still aren't quite identical, as banding occurs for the outer data points. This is in fact intentional, such that the boundaries of the data cloud stay visible to the viewer. How strong the banding appears, depends on the point density, i.e. the number of points in the plot. For some situations with scatter plots it might thus be desirable to manually turn adaptive sampling off. For example, when saving the plot to disk. This can be achieved by setting \a enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled back to true afterwards. */ void QCPGraph::setAdaptiveSampling(bool enabled) { mAdaptiveSampling = enabled; } /*!

This is realized by introducing a third coordinate \a t, which defines the order of the points described by the other two coordinates \a x and \a y. To plot data, assign it with the \ref setData or \ref addData functions. Gaps in the curve can be created by adding data points with NaN as key and value (qQNaN() or std::numeric_limits::quiet_NaN()) in between the two data points that shall be separated. \section appearance Changing the appearance The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush). \section usage Usage Like all data representing objects in QCustomPlot, the QCPCurve is a plottable (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies (QCustomPlot::plottable, QCustomPlot::addPlottable, QCustomPlot::removePlottable, etc.) Usually, you first create an instance and add it to the customPlot: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1 and then modify the properties of the newly created plottable, e.g.: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2 */ /*! Constructs a curve which uses \a keyAxis as its key axis ("x") and \a valueAxis as its value axis ("y"). \a keyAxis and \a valueAxis must reside in the same QCustomPlot instance and not have the same orientation. If either of these restrictions is violated, a corresponding message is printed to the debug output (qDebug), the construction is not aborted, though. The constructed QCPCurve can be added to the plot with QCustomPlot::addPlottable, QCustomPlot then takes ownership of the graph. */ QCPCurve::QCPCurve(QCPAxis *keyAxis, QCPAxis *valueAxis) : QCPAbstractPlottable(keyAxis, valueAxis) { mData = new QCPCurveDataMap; mPen.setColor(Qt::blue); mPen.setStyle(Qt::SolidLine); mBrush.setColor(Qt::blue); mBrush.setStyle(Qt::NoBrush); mSelectedPen = mPen; mSelectedPen.setWidthF(2.5); mSelectedPen.setColor(QColor(80, 80, 255)); // lighter than Qt::blue of mPen mSelectedBrush = mBrush; setScatterStyle(QCPScatterStyle()); setLineStyle(lsLine); } QCPCurve::~QCPCurve() { delete mData; } /*!

In situations where a single segment skips over multiple regions it might become necessary to add extra points at the corners of region 5 (see \ref getRegion) such that the optimized segment doesn't unintentionally cut through the visible area of the axis rect and create plot artifacts. This method provides these points that must be added, assuming the original segment doesn't start, end, or traverse region 5. (Corner points where region 5 is traversed are calculated by \ref getTraverseCornerPoints.) For example, consider a segment which directly goes from region 4 to 2 but originally is far out to the top left such that it doesn't cross region 5. Naively optimizing these points by projecting them on the top and left borders of region 5 will create a segment that surely crosses 5, creating a visual artifact in the plot.

The width of the individual bars can be controlled with \ref setWidthType and \ref setWidth. Bar charts are stackable. This means, two QCPBars plottables can be placed on top of each other (see \ref QCPBars::moveAbove). So when two bars are at the same key position, they will appear stacked.

Else, the backbone line might exceed the whisker bars by a few pixels due to the pen cap being not perfectly flat. The Outlier data points are drawn as normal scatter points. Their look can be controlled with \ref setOutlierStyle \section usage Usage Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable. Usually, you first create an instance and add it to the customPlot: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1 and then modify the properties of the newly created plottable, e.g.: \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2 */ /*!

\class QCPColorMapData \brief Holds the two-dimensional data of a QCPColorMap plottable. This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a color, depending on the value. The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize). Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref setKeyRange, \ref setValueRange). The data cells can be accessed in two ways: They can be directly addressed by an integer index with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are provided by the functions \ref coordToCell and \ref cellToCoord. This class also buffers the minimum and maximum values that are in the data set, to provide QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value that is greater than the current maximum increases this maximum to the new value. However, setting the cell that currently holds the maximum value to a smaller value doesn't decrease the maximum again, because finding the true new maximum would require going through the entire data array, which might be time consuming. The same holds for the data minimum. This functionality is given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience parameter \a recalculateDataBounds which may be set to true to automatically call \ref recalculateDataBounds internally. */ /* start of documentation of inline functions */ /*! \fn bool QCPColorMapData::isEmpty() const Returns whether this instance carries no data.

Blue dotted circles are anchors, solid blue discs are positions." The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt the coordinate axes of the graph and update its \a position to be on the graph's data. This means the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a position will have no effect because they will be overriden in the next redraw (this is when the coordinate update happens). If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will stay at the corresponding end of the graph. With \ref setInterpolating you may specify whether the tracer may only stay exactly on data points or whether it interpolates data points linearly, if given a key that lies between two data points of the graph. The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer have no own visual appearance (set the style to \ref tsNone), and just connect other item positions to the tracer \a position (used as an anchor) via \ref QCPItemPosition::setParentAnchor. \note The tracer position is only automatically updated upon redraws. So when the data of the graph changes and immediately afterwards (without a redraw) the a position coordinates of the tracer are retrieved, they will not reflect the updated data of the graph.
