\n\n## What is a sparkline?\n\nA sparkline is a very small chart, typically drawn without axes or coordinates. It presents the general shape of the variation (typically over time) in some measurement, such as temperature or stock market price, in a simple and highly condensed way. Sparklines are small enough to be embedded in text, or several sparklines may be grouped together as elements of a small multiple. Whereas the typical chart is designed to show as much data as possible, and is set off from the flow of text, sparklines are intended to be succinct, memorable, and located where they are discussed.\n\n[Source: Wikipedia](https://en.wikipedia.org/wiki/Sparkline)\n\n## What ISN'T a sparkline?\n\n`DSFSparkline` **IS NOT** designed to be a full-featured graphing library. It was built to be lightweight, to create small, memorable charts within an app.\n\nIf you need features like labelling, real-time updating, axis-labelling, interactivity, legends or beautiful charts at larger sizes, you might be better served by the [Charts library](https://github.com/danielgindi/Charts), [Core plot](https://github.com/core-plot/core-plot) or [SciChart (paid)](https://www.scichart.com/ios-chart-features/). You can find a whole lot more [here](https://iosexample.com/tag/charts/).\n\n## Features\n\n* Multiple graph styles support, such as line, bar, tablet etc.\n* Support for sparkline customizations, such as zero-line, grid lines, highlighting.\n* Prebuilt NSView/UIView/SwiftUI types for quick integration\n* Independently scalable for sparklines at any size\n* y-range can automatically grow or shrink to encompass the full y-range of data.\n* y-range can be fixed and the sparkline will truncate to the specified range\n* SwiftUI support for all sparkline types\n* NSAttributedString support\n* `IBDesignable` support for prebuilt types so you can see and configure your sparklines in interface builder.\n* Optional drawing of a 'zero line' on the bar and line graphs (thanks [Tito Ciuro](https://github.com/tciuro))\n* Playground support\n\n## TL;DR - Show me something!\n\n
\nCreate a retina-scale (144dpi) bitmap with a simple line overlay graph\n\n```swift\n// A datasource with a simple set of data\nlet source = DSFSparkline.DataSource(values: [4, 1, 8, 7, 5, 9, 3], range: 0 ... 10)\n\nlet bitmap = DSFSparklineSurface.Bitmap() // Create a bitmap surface\nlet stack = DSFSparklineOverlay.Line() // Create a line overlay\nstack.dataSource = source // Assign the datasource to the overlay\nbitmap.addOverlay(stack) // And add the overlay to the surface.\n\n// Generate an image with retina scale\nlet image = bitmap.image(width: 50, height: 25, scale: 2)\n\n// Embed a sparkline in an NSAttributedString\nlet attributedString = bitmap.attributedString(size: CGSize(width: 40, height: 18), scale: 2)\n```\n\n\n\n
\n\n
\nCreate a Swift-UI line graph sparkline with zero-line and highlight range overlays\n\n```swift\nfileprivate let SwiftUIDemoDataSource: DSFSparkline.DataSource = {\n let d = DSFSparkline.DataSource(windowSize: 20, range: 0 ... 1, zeroLineValue: 0.5)\n d.push(values: [\n 0.72, 0.84, 0.15, 0.16, 0.30, 0.58, 0.87, 0.44, 0.02, 0.27,\n 0.48, 0.16, 0.15, 0.14, 0.81, 0.53, 0.67, 0.52, 0.07, 0.50\n ])\n return d\n }()\n\nstruct SuperCoolLineSpark: View {\n // The overlay representing the zero-line for the data source\n var zeroOverlay: DSFSparklineOverlay = {\n let zeroLine = DSFSparklineOverlay.ZeroLine()\n zeroLine.dataSource = SwiftUIDemoDataSource\n zeroLine.dashStyle = []\n return zeroLine\n }()\n\n // The overlay to draw a highlight between range 0 ..< 0.2\n var rangeOverlay: DSFSparklineOverlay = {\n let highlight = DSFSparklineOverlay.RangeHighlight()\n highlight.dataSource = SwiftUIDemoDataSource\n highlight.highlightRange = 0.0 ..< 0.2\n highlight.fill = DSFSparkline.Fill.Color(DSFColor.gray.withAlphaComponent(0.4).cgColor)\n return highlight\n }()\n\n // The actual line graph\n var lineOverlay: DSFSparklineOverlay = {\n let lineOverlay = DSFSparklineOverlay.Line()\n lineOverlay.dataSource = SwiftUIDemoDataSource\n\n lineOverlay.primaryStrokeColor = DSFColor.systemBlue.cgColor\n lineOverlay.primaryFill = DSFSparkline.Fill.Color(DSFColor.systemBlue.withAlphaComponent(0.3).cgColor)\n\n lineOverlay.secondaryStrokeColor = DSFColor.systemYellow.cgColor\n lineOverlay.secondaryFill = DSFSparkline.Fill.Color(DSFColor.systemYellow.withAlphaComponent(0.3).cgColor)\n\n lineOverlay.strokeWidth = 1\n lineOverlay.markerSize = 4\n lineOverlay.centeredAtZeroLine = true\n\n return lineOverlay\n }()\n\n var body: some View {\n DSFSparklineSurface.SwiftUI([\n rangeOverlay, // range highlight overlay\n zeroOverlay, // zero-line overlay\n lineOverlay, // line graph overlay\n ])\n .frame(width: 150, height: 40)\n }\n}\n```\n\n\n\n
\n\n## Integration\n\nUse Swift Package Manager to integrate `DSFSparkline` into your project\n\nAdd `https://github.com/dagronf/DSFSparkline` to your project.\n\n### Note\n\nWhen adding `DSFSparkline` to one of your projects, you need to choose a **SINGLE** 'package product' to \nlink to your target. Choosing multiple package products for your project will result in weird, inconsistent link errors.\n\n| Package Product | Description |\n|:-----------------------|:--------------------------------|\n| `DSFSparkline` | The default style. If you are just trying this library out, this is the one to choose\n| `DSFSparkline-static` | Add `DSFSparkline` as a STATIC library, meaning that all DSFSparkline code is linked directly into your target |\n| `DSFSparkline-shared` | Add `DSFSparkline` as a SHARED library, meaning that you can use a single shared framework between multiple targets in your project to save space |\n\n\n\n\n\n## Available graph types\n\n### Line \n\nA simple line sparkline. The line can be centered around a zero line to indicate positive and negative values. You can also add (optional) markers to the data points.\n\nYou can custom-draw the markers by supplying a drawing callback block (`markerDrawingBlock`) where you can customize which markers are drawn (for example, just the min and max values) and how they are drawn.\n\n| Standard | Centered |\n|------------|------------|\n|||\n\n| Interpolated | Interpolated Centered |\n|------------|------------|\n|||\n\n| Standard Markers | Interpolated Markers |\n|------------|------------|\n|||\n\n| Custom Markers (min/max only) | Custom Markers (Last 5 values) |\n|------------|------------|\n|||\n\n
\n Swift example using custom markers\n \n```swift\n//\n// A custom marker drawing function that draws the maximum value in green, the minimum value in red\n//\nself.myLineView.markerDrawingBlock = { context, markerFrames in\n // Get the frames containing the minimum and maximum values\n if let minMarker = markerFrames.min(by: { (a, b) -> Bool in a.value < b.value }),\n let maxMarker = markerFrames.min(by: { (a, b) -> Bool in a.value > b.value }) {\n\n // Draw minimum marker\n\n context.setFillColor(DSFColor.systemRed.cgColor)\n context.fill(minMarker.rect)\n context.setLineWidth(0.5)\n context.setStrokeColor(DSFColor.white.cgColor)\n context.stroke(minMarker.rect)\n\n // Draw maximum marker\n\n context.setFillColor(DSFColor.systemGreen.cgColor)\n context.fill(maxMarker.rect)\n\n context.setLineWidth(0.5)\n context.setStrokeColor(DSFColor.white.cgColor)\n context.stroke(maxMarker.rect)\n }\n}\n```\n
\n\n### Bar \n\nA simple barchart sparkline. The bar can be centered around a zero line to indicate positive and negative values.\n\n| Standard | Centered |\n|------------|------------|\n|||\n\n### Stackline \n\nA stackline sparkline is similar to a bar chart except that it doesn't separate out individual columns. The stackline can be centered around a zero line to indicate positive and negative values.\n\n| Standard | Centered |\n|------------|------------|\n|||\n\n### Stripes \n\nA stripes graph. A good example of a stripes graph is the 'warming stripes' [climate graph](https://www.climatecentral.org/showyourstripes).\n\nValues from the datasource are mapped to a supplied gradient\n\n| Standard | Integral (pixel boundaries) |\n|------------|-------------------------------|\n|||\n\n### Dot \n\nA dot sparkline reminiscent of Activity Viewer's CPU history graphs\n\n| Standard | Inverted |\n|------------|------------|\n|||\n\n### Win/Loss/Tie \n\nA win-loss graph, where positive values in the datasource are represented as a 'win', negative values represented as a 'loss', and zero values are a 'tie'.\n\n| Win/Loss | Win/Loss/Tie |\n|------------|------------|\n|||\n\n### Tablet \n\nA tablet graph, where positive values in the datasource are represented as a filled circle, negative values represented as an unfilled circle. The behaviour is identical to the win/loss graph.\n\n| Standard |\n|------------|\n||\n\n### Pie \n\nA basic pie sparkline\n\n| Standard |\n|------------|\n||\n\n### DataBar \n\nA databar sparkline. Supports percentage and totals types.\n\n| Percent | Total |\n|------------|------------|\n|||\n\n### PercentBar \n\nA percentbar sparkline takes a single value (0 ... 1) and draws a horizontal bar chart containing the value with an optional text label.\n\n| | |\n|------------|------------|\n|||\n\n### WiperGauge \n\nA simple gauge with a single value (0 ... 1). The color displayed in the gauge can be one of\n\n* a single flat color\n* a color mapped from a gradient to the value\n* a color mapped from a color bucket to the value\n\n| Standard |\n|------------|\n||\n\n### Activity Grid \n\nA Github-style activity grid. Each cell represents a discrete value in a progression with a color\n\n* Configurable horizontal/vertical cell count\n* Configurable cell spacing\n* Configurable fill schemes\n\n| | |\n|------------|------------|\n|||\n\n### Circular Progress \n\nA circular progress graph\n\n* Configurable track width\n* Optional track background color\n* Configurable track padding to allow overlaying multiple progress graphs to replicate the health rings.\n* Configurable fill schemes\n\n| Simulated health rings |\n|------------------------|\n|   |\n\n### Circular Gauge \n\nA circular gauge\n\n* Configurable track/line width\n* Configurable fill/stroke schemes\n* Supports shadows/inner shadows\n* Animatable changes\n\n| | | | |\n|------|-------|-------|-------|\n| | | | |\n\n\n# Demos\n\nYou can find a lot of examples of sparklines in projects in the `Demos/Samples` subfolder, providing examples for macOS (swift and objc), iO, tvOS, macCatalyst and SwiftUI.\n\nThere's also a simple Xcode Playground available in the `Demos/Playground` subfolder where you can play with the different sparkline types\n\n# Building your sparkline\n\n### Using prebuilt views\n\nA prebuilt view is useful to quickly add a sparkline using SwiftUI or via Interface Builder. These views a slightly more limited set of styling and customizations but are much quicker to implement than using overlays directly.\n\nFor the most part, the prebuilt types will be all you need.\n\nIf you've used `DSFSparklines` prior to v4, these are the original view types that you used to display your sparklines.\n\n* **A datasource** - the set of values to draw\n* **A prebuilt view type** - the NSView/UIView/SwiftUI view to draw your sparkline\n\n### Using overlays\n\nThere are three fundamental building blocks for an overlay sparkline. Overlay sparklines are more flexible and configurable than the pre-built views, but are more complex to set up.\n\n* **A surface** - where it will draw\n* **A datasource** - the set of values to draw\n* **One or more overlays** - the 'layers' which render different components of the sparkline\n\n## Surface\n\nA surface represents a destination for a sparkline. This library provides a number of built-in surfaces\n\n* `DSFSparklineSurfaceView` - An `NSView`/`UIView` surface for displaying a sparkline\n* `DSFSparklineSurface.SwiftUI` - A SwiftUI `View` surface.\n* `DSFSparklineSurface.Bitmap` - A `NSImage`/`UIImage`/`CGImage`/`NSAttributedString` surface for creating a bitmap from a sparkline.\n\n## DataSource\n\nA data source provides data for a sparkline. A datasource can be shared between multiple overlays or prebuilt types (see below) to provide different 'views' of the data contained within the source. And if a `DataSource` is updated, all sparkline ovelays observing that source will be automatically re-rendered.\n\nThere are currently two types of datasource available\n\n### DSFSparkline.DataSource\n\nA DataSource that contains values that can be updated by pushing new values into the source.\n\n
\n More details\n\n#### WindowSize\n\nThe DataSource defines a 'windowSize' - the maximum number of values to be drawn on the overlay. As values are pushed into the DataSource, any values that no longer `fit` within the DataSource window are discarded.\n\n* If the window size is reduced, stored data is truncated.\n* If the window size is increased, the data store is padded with zeros\n\n
\n Code example\n\n```swift\n/// Swift\ndataSource.windowSize = 30\nassert(dataSource.windowSize == 30)\n```\n\n```objective-c\n/// Objective-C\n[dataSource setWindowSize:30];\nassert([dataSource windowSize] == 30);\n```\n
\n\n#### Y-range\n\nThe range defines the upper and lower values to be displayed in the sparkline. Any values pushed into the datasource will be capped when drawn to this range.\n\nIf the range is not set (ie nil), then any overlays will automatically resize to fit the entire range of values within the source. For example, with values as [1, 2, 3, 4] the range is implicitly set as 1 ... 4. If the values are [-10, 100, 33] the range is implicitly set as -10 ... 100\n\n
\n Code example\n\n```swift\n/// Swift\ndataSource.range = -1.0 ... 1.0\n```\n\n```objective-c\n/// Objective-C\n[dataSource setRangeWithLowerBound:-1.0 upperBound:1.0];\n```\n
\n\n#### Zero-line value\n\nThe zero-line defines the point the sparkline overlays should consider to be 'zero'. For example, graphs that can be centered (line, bar and stackline) use the zero-line value to define where the graph is centered around.\n\nThe zero-line value defaults to zero.\n\nYou can draw a zero-line for a sparkline by adding a `DSFSparklineOverlay.ZeroLine` to your surface.\n\n
\n Code example\n\n```swift\n/// Swift\ndataSource.zeroLineValue = 0.2\n```\n\n```objc\n/// Objective-C\n[dataSource setZeroLineValue:0.2];\n```\n
\n\n#### Adding values\n\nYou can push new values into the datasource using the `push` functions. Values in the datasource older than the datasource's `windowSize` are discarded. \n\nAs values are pushed into the datasource, any overlays assigned this datasource will automatically update.\n\n
\n Code example\n\n```swift\n/// Swift\ndataSource.push(value: 4.5)\ndataSource.push(values: [6, 7, 8])\n```\n\n```objective-c\n/// Objective-C\n[dataSource pushWithValue:@(4.5)];\n```\n
\n\nYou replace all the values in a datasource the `set` functions. The set function also changes the `windowSize` for the datasource to the size of the values array passed in.\n\nAny overlays assigned this datasource will automatically update.\n\n
\n Code example\n\n```swift\n/// Swift\ndatasource.set(values: [\n 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0,\n 0.0, -0.1, -0.2, -0.3, -0.4, -0.5, -0.6, -0.7, -0.8, -0.9, -1.0\n])\n```\n\n```objc\n/// Objective-C\n[datasource setWithValues:\n @[@(0.0), @(0.1), @(0.2), @(0.3), @(0.4), @(0.5), @(0.6), @(0.7), @(0.8), @(0.9), @(1),\n @(0.0), @(-0.1), @(-0.2), @(-0.3), @(-0.4), @(-0.5), @(-0.6), @(-0.7), @(-0.8), @(-0.9), @(-1)]];\n```\n\n
\n\n\n
\n\n### DSFSparkline.StaticDataSource\n\nA datasource that contains a static set of values. Some types of sparkline use a single 'set' of data, providing no historical context.\n\n
\n More details \n\n```swift\n/// Swift\nlet dataSource = DSFSparkline.StaticDataSource([1, 2, 3])\n```\n\n```objc\n/// Objective-C\nDSFSparklineStaticDataSource* dataSource = [[DSFSparklineStaticDataSource alloc] init: @[@(1), @(2), @(3)]];\n```\n\n
\n\n## Overlays\n\nOverlays represent the individual visual components of a sparkline. You can add as many or as few to your surface in any order. For example, you could overlay two different graph types onto the same surface using the same. And as overlays can share their datasource, all overlays using the same source will automatically update if the data changes (for example, in reponse to a `push`)\n\nFor example, there is an overlay that highlights a y-range of data. Or, if you want some grid lines, you can add them using the gridlines overlay.\n\nYou can add different instances of an overlay to the same sparkline. For example, if you want to add multiple range highlights you add multiple 'highlight' overlays to the sparkline surface.\n\nThe order in which the overlays are added determine where in the z-order that they appear in the sparkline. For example, you can choose to draw the grid on top of the graph if you want by adding the graph overlay BEFORE you add the grid overlay\n\n
\n\nThe overlay allows your sparkline to be as complex or as simple as you want.\n\n### Graph types\n\n#### Dynamic\n\nA dynamic graph automatically updates its overlays as values are 'pushed' onto its datasource. As data is added the assigned overlay is automatically updated to reflect the new data. If more data is added via a push or set the data is added to the datasource, the associated view will automatically update to reflect the new data. Older data that no longer falls within the datasource window is discarded.\n\nThis provides the ability to show a historical data set over the breadth of the graph.\n\n

\n\n## Screenshots\n\n### In app\n\n| macOS dark | macOS light | iOS |\n|----|----|----|\n| | | |\n\n### Interface Builder\n\n| macOS | tvOS |\n|----|----|\n|||\n\n### SwiftUI\n\n\n\n### NSAttributedString support\n\n\n\n### Animated\n\n![](https://github.com/dagronf/dagronf.github.io/raw/master/art/projects/DSFSparkline/DSFSparkline_lots.gif)\n\n## Changes\n\n### `7.0.0`\n\n* Removed support for macOS 10.11, 10.12\n* Removed support for iOS 13, tvOS 13\n* Removed CocoaPods support (if you need Cocoapods, stick with v6).\n\n### `6.0.0`\n\n* Added CircularGauge, CircularProgress sparkline types\n* Removed support for `@IBDesignable` and `@IBInspectable` from the NSView/UIView implementations, as Xcode has indicated that it will be dropping support in the near future\n\n### `5.2.0`\n\n* Added grid-lines support for pre-built views (line, bar, stack) (NSView/UIView/SwiftUI)\n\n### `5.1.0`\n\n* Added Activity Grid\n\n### `5.0.0`\n\n* Fixed [occasional clipping](https://github.com/dagronf/DSFSparkline/issues/13) on interpolated line graphs.\n\n### `4.6.0`\n\n* Added WiperGauge sparkline type\n\n### `4.3.0`\n\n* Added the ability to custom-draw markers for the 'line' sparkline type [(raised issue)](https://github.com/dagronf/DSFSparkline/issues/6)\n* Fixed a minor issue where insetting certain graph types to remove clipping (line with markers, bar) would mean that zeroline, highlight overlays and grids would be appear to be very slightly off.\n\n### `4.2.0`\n\n* Added 'percent bar' sparkline type.\n\n### `4.1.2`\n\n* Fixed compile issue [Cannot find type 'NSTextAttachment' in scope\" crashes when using SwiftPackage](https://github.com/dagronf/DSFSparkline/issues/5)\n\n### `4.1.1`\n\n* Fixed gradient bucket count issue. \n* Added AttributedString SwiftUI demo to the ReportView demo. Demo uses [The SwiftUI Lab Attributed String](https://swiftui-lab.com/attributed-strings-with-swiftui/) with AppKit bug fix for width calculation.\n\n### `4.1.0`\n\n* Embed sparklines in NSAttributedString.\n\n### `4.0.0`\n\nSubstantial re-architect of the drawing code (that used to be directly in the views) into overlays and surfaces that are far more flexible (for example, being able to draw a sparkline bitmap without having to create a view)\n\nThe previous view/swiftui types are still available - they have been rebuilt on using the new overlay scheme and are referred to in documentation as 'prebuilt' types. This allowed backwards compatibility with previous versions of the library. Note however that given that the prebuilt views have been re-written there is a possibility of slight visual differences.\n\n### `3.7.0`\n\n* Added stripe graph\n\n### `3.6.1`\n\n* Fixed animations on iOS/tvOS\n\n### `3.6.0`\n\n* Added pie chart, databar chart.\n* Added ability to show data markers for line graphs\n\n### `3.5.2`\n\n* Fixed Objective-C Demo app\n* Added `snapshot` method to the base sparkline view class to produce an NSImage/UIImage version of the sparkline for embedded sparklines in text etc.\n\n### `3.5.1`\n\n* Fixed version in podspec\n\n### `3.5.0`\n\n* Added stackline sparkline type\n* Added win/loss/tie sparkline type\n* Added tablet sparkline type\n\n### `3.4.0`\n\n* Added support for centering line and bar graphs around their zero-line value.\n\n### `3.3.0`\n\n* Fixed issue where iOS background wasn't being drawn correctly in some cases.\n* Fixed rare crash where a line graph with < 2 points would crash.\n\n### `3.2.0`\n\n* Changed the zero-line definition class to `DSFSparklineZeroLineDefinition` for clarity.\n* More documentation, especially around SwiftUI. Attempted to make the documentation clearer around drawing parameters.\n\n### `3.1.0`\n\n* Add the ability to customize the zero-line display ([Tito Ciuro](https://github.com/tciuro))\n* Changed `showZero` to `showZeroLine` for consistency with the new zero-line display values\n\n### `3.0.0`\n\n* Add the ability to set the 'zero' line value. Defaults to zero for backwards compatibility.\n\nYou can set where the 'zero' line draws via the `zeroLineValue` on the datasource.\n\n### `2.0.0`\n\n* The primary views have been renamed with a `View` postfix. So\n\n `DSFSparklineLineGraph` -> `DSFSparklineLineGraphView`\n \n `DSFSparklineBarGraph` -> `DSFSparklineBarGraphView`\n \n `DSFSparklineDotGraph` -> `DSFSparklineDotGraphView`\n\n* Renamed `SLColor` and `SLView` to `DSFColor` and `DSFView` for module naming consistency.\n\n* I removed `windowSize` from the core `DSFSparklineDataSourceView`. `windowSize` is related to data, and should never have been part of the UI definition. I've provided a replacement purely for `IBDesignable` support called `graphWindowSize` which should only be called from Interface Builder. If you want to set the windowSize from your xib file, set the `graphWindowSize` inspectable.\n\n\tIf you see warnings in the log like \n`2020-12-07 18:22:51.619867+1100 iOS Sparkline Demo[75174:1459637] Failed to set (windowSize) user defined inspected property on (DSFSparkline.DSFSparklineBarGraphView): [ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key windowSize.\n`\nit means that you have a `windowSize` value set in your .xib file. Remove it and set the `graphWindowSize` value instead.\n\n* For the Bar type, `lineWidth` and `barSpacing` now represent the pixel spacing between bars and the pixel width for the line. You may find that your line spacing and bar spacing are now incorrect if you have set fractional values for these in the past (for example, if you set lineWidth = 0.5).
