"content": "## Googlecharts\n\n[](https://travis-ci.org/mattetti/googlecharts)\n\nThe goal of this Gem is to make the creation of Google Charts a simple and easy task.\n \n require 'googlecharts'\n Gchart.line( :size => '200x300', \n :title => \"example title\",\n :bg => 'efefef',\n :legend => ['first data set label', 'second data set label'],\n :data => [10, 30, 120, 45, 72])\n \n\nCheck out the [full documentation over there](http://googlecharts.rubyforge.org/)\n\nThis gem is fully tested using Rspec, check the rspec folder for more examples.\n\nSee at the bottom of this file who reported using this gem.\n\nChart Type\n-------------\n\nThis gem supports the following types of charts:\n \n * line, \n * line_xy\n * sparkline\n * scatter\n * bar\n * venn\n * pie\n * pie_3d\n * google meter\n \nGooglecharts also supports graphical themes and you can easily load your own.\n\nTo create a chart, simply require Gchart and call any of the existing type:\n\n require 'gchart'\n Gchart.pie\n \n \nChart Title\n-------------\n\n To add a title to a chart pass the title to your chart:\n \n Gchart.line(:title => 'Sexy Charts!')\n \nYou can also specify the color and/or size\n \n Gchart.line(:title => 'Sexy Charts!', :title_color => 'FF0000', :title_size => '20')\n\nColors\n-------------\n\nSpecify a color with at least a 6-letter string of hexadecimal values in the format RRGGBB. For example:\n\n * FF0000 = red\n * 00FF00 = green\n * 0000FF = blue\n * 000000 = black\n * FFFFFF = white\n\nYou can optionally specify transparency by appending a value between 00 and FF where 00 is completely transparent and FF completely opaque. For example:\n\n * 0000FFFF = solid blue\n * 0000FF00 = transparent blue\n\nIf you need to use multiple colors, check the doc. Usually you just need to pass :attribute => 'FF0000,00FF00'\n\nSome charts have more options than other, make sure to refer to the documentation.\n\nBackground options:\n-------------\n\nIf you don't set the background option, your graph will be transparent.\n\n* You have 3 types of background http://code.google.com/apis/chart/#chart_or_background_fill\n\n- solid\n- gradient\n- stripes\n\nBy default, if you set a background color, the fill will be solid:\n\n Gchart.bar(:bg => 'efefef')\n\nHowever you can specify another fill type such as:\n \n Gchart.line(:bg => {:color => 'efefef', :type => 'gradient'})\n \nIn the above code, we decided to have a gradient background, however since we only passed one color, the chart will start by the specified color and transition to white. By the default, the gradient angle is 0. Change it as follows:\n\n Gchart.line(:title =>'bg example', :bg => {:color => 'efefef', :type => 'gradient', :angle => 90})\n \nFor a more advance use of colors, refer to http://code.google.com/apis/chart/#linear_gradient\n\n Gchart.line(:bg => {:color => '76A4FB,1,ffffff,0', :type => 'gradient'})\n \n \nThe same way you set the background color, you can also set the graph background:\n\n Gchart.line(:graph_bg => 'cccccc')\n \nor both\n\n Gchart.line(:bg => {:color => '76A4FB,1,ffffff,0', :type => 'gradient'}, :graph_bg => 'cccccc', :title => 'Sexy Chart')\n \n \nAnother type of fill is stripes http://code.google.com/apis/chart/#linear_stripes\n\n Gchart.line(:bg => {:color => 'efefef', :type => 'stripes'})\n \nYou can customize the amount of stripes, colors and width by changing the color value.\n\n\nThemes\n--------\n\n Googlecharts comes with 4 themes: keynote, thirty7signals, pastel and greyscale. (ganked from [Gruff](http://github.com/topfunky/gruff/tree/master)\n\n\n Gchart.line(\n :theme => :keynote, \n :data => [[0,40,10,70,20],[41,10,80,50,40],[20,60,30,60,80],[5,23,35,10,56],[80,90,5,30,60]], \n :title => 'keynote'\n )\n\n * keynote\n\n \n\n * thirty7signals\n\n \n\n * pastel\n\n \n\n * greyscale\n\n \n\n\nYou can also use your own theme. Create a yml file using the same format as the themes located in lib/themes.yml\n\nLoad your theme(s):\n\n Chart::Theme.add_theme_file(\"#{File.dirname(__FILE__)}/fixtures/another_test_theme.yml\")\n\nAnd use the standard method signature to use your own theme:\n\n Gchart.line(:theme => :custom_theme, :data => [[0, 40, 10, 70, 20],[41, 10, 80, 50]], :title => 'greyscale')\n\n \n \nLegend & Labels\n-------------\n\nYou probably will want to use a legend or labels for your graph.\n\n Gchart.line(:legend => 'legend label')\nor\n Gchart.line(:legend => ['legend label 1', 'legend label 2'])\n \nWill do the trick. You can also use the labels alias (makes more sense when using the pie charts)\n\n chart = Gchart.pie(:labels => ['label 1', 'label 2'])\n\nMultiple axis labels \n-------------\n\nMultiple axis labels are available for line charts, bar charts and scatter plots.\n\n* x = bottom x-axis\n* t = top x-axis\n* y = left y-axis\n* r = right y-axis\n\n Gchart.line(:axis_with_label => 'x,y,r,t')\n \nTo add labels on these axis:\n\n Gchart.line(:axis_with_label => 'x,y,r,t',\n :axis_labels => ['Jan|July|Jan|July|Jan', '0|100', 'A|B|C', '2005|2006|2007'])\n\nNote that each array entry could also be an array but represent the\nlabels for the corresponding axis.\n\nA question which comes back often is how do I only display the y axis\nlabel? Solution:\n\n Gchart.line(\n :data => [0,20, 40, 60, 140, 230, 60],\n :axis_with_labels => 'y')\n\nCustom axis ranges\n---------------\n\nIf you want to display a custom range for an axis, you need to set the\nrange as described in the Google charts documentation: min, max, step:\n\n Gchart.line( :data => [17, 17, 11, 8, 2], \n :axis_with_labels => ['x', 'y'], \n :axis_labels => [['J', 'F', 'M', 'A', 'M']], \n :axis_range => [nil, [2,17,5]])\n\n\nIn this case, the custom axis range is only defined for y (second\nentry) with a minimum value of 2, max 17 and a step of 5.\n\nThis is also valid if you want to set a x axis and automatically define\nthe y labels.\n \n\nData options\n-------------\n\nData are passed using an array or a nested array. \n\n Gchart.bar(:data => [1,2,4,67,100,41,234]) \n \n Gchart.bar(:data => [[1,2,4,67,100,41,234],[45,23,67,12,67,300, 250]])\n \nBy default, the graph is drawn with your max value representing 100% of the height or width of the graph. You can change that my passing the max value.\n\n Gchart.bar(:data => [1,2,4,67,100,41,234], :max_value => 300)\n Gchart.bar(:data => [1,2,4,67,100,41,234], :max_value => 'auto')\n \nor if you want to use the real values from your dataset:\n\n Gchart.bar(:data => [1,2,4,67,100,41,234], :max_value => false)\n \n \nYou can also define a different encoding to add more granularity:\n\n Gchart.bar(:data => [1,2,4,67,100,41,234], :encoding => 'simple') \n Gchart.bar(:data => [1,2,4,67,100,41,234], :encoding => 'extended') \n Gchart.bar(:data => [1,2,4,67,100,41,234], :encoding => 'text') \n \n\nPies:\n-------------\n \nyou have 2 type of pies:\n - Gchart.pie() the standard 2D pie\n _ Gchart.pie_3d() the fancy 3D pie\n \nTo set labels, you can use one of these two options:\n\n @legend = ['Matt_fu', 'Rob_fu']\n Gchart.pie_3d(:title => @title, :labels => @legend, :data => @data, :size => '400x200')\n Gchart.pie_3d(:title => @title, :legend => @legend, :data => @data, :size => '400x200')\n \nBars:\n-------------\n\nA bar chart can accept options to set the width of the bars, spacing between bars and spacing between bar groups. To set these, you can either provide a string, array or hash.\n\nThe Google API sets these options in the order of width, spacing, and group spacing, with both spacing values being optional. So, if you provide a string or array, provide them in that order:\n\n Gchart.bar(:data => @data, :bar_width_and_spacing => '25,6') # width of 25, spacing of 6\n Gchart.bar(:data => @data, :bar_width_and_spacing => '25,6,12') # width of 25, spacing of 6, group spacing of 12\n Gchart.bar(:data => @data, :bar_width_and_spacing => [25,6]) # width of 25, spacing of 6\n Gchart.bar(:data => @data, :bar_width_and_spacing => 25) # width of 25\n \nThe hash lets you set these values directly, with the Google default values set for any options you don't include:\n\n Gchart.bar(:data => @data, :bar_width_and_spacing => {:width => 19})\n Gchart.bar(:data => @data, :bar_width_and_spacing => {:spacing => 10, :group_spacing => 12})\n\nRadar:\n-------------\n In a Radar graph, the x-axis is circular. The points can be connected by straight lines or curved lines.\n Gchart.radar(:data => @data, :curved => true)\n\nSparklines:\n-------------\n\nA sparkline chart has exactly the same parameters as a line chart. The only difference is that the axes lines are not drawn for sparklines by default.\n \n\nGoogle-o-meter\n-------------\n\nA Google-o-meter has a few restrictions. It may only use a solid filled background and it may only have one label.\n\nRecord Chart PNG file in filesystem Sample :\n--------------------------------------------\n\nMulti Lines Chart Sample :\n\n\tchart = Gchart.new(\t:type => 'line',\n\t\t\t\t\t\t:title => \"example title\",\n\t\t\t\t\t\t:theme => :keynote,\n\t\t\t\t\t\t:data => [[17, 17, 11, 8, 2],[10, 20, 15, 5, 7],[2, 3, 7, 9, 12]], \n\t\t\t\t\t\t:line_colors => 'e0440e,e62ae5,287eec',\n\t\t\t\t\t\t:legend => ['courbe 1','courbe 2','courbe 3'],\n\t\t\t\t\t\t:axis_with_labels => ['x', 'y'], \n\t\t\t\t\t\t:axis_range => [[0,100,20], [0,20,5]],\n\t\t\t\t\t\t:filename => \"tmp/chart.png\")\n\t\t\t\n\t# Record file in filesystem\n\tchart.file\n\ntry yourself\n-------------\n\n Gchart.bar( :data => [[1,2,4,67,100,41,234],[45,23,67,12,67,300, 250]], \n :title => 'SD Ruby Fu level', \n :legend => ['matt','patrick'], \n :bg => {:color => '76A4FB', :type => 'gradient'}, \n :bar_colors => 'ff0000,00ff00')\n\n \"http://chart.apis.google.com/chart?chs=300x200&chdl=matt|patrick&chd=s:AAANUIv,JENCN9y&chtt=SDRuby+Fu+level&chf=bg,lg,0,76A4FB,0,ffffff,1&cht=bvs&chco=ff0000,00ff00\" \n \n Gchart.pie(:data => [20,10,15,5,50], :title => 'SDRuby Fu level', :size => '400x200', :labels => ['matt', 'rob', 'patrick', 'ryan', 'jordan'])\nhttp://chart.apis.google.com/chart?cht=p&chs=400x200&chd=s:YMSG9&chtt=SDRuby+Fu+level&chl=matt|rob|patrick|ryan|jordan\n"
