Colors can be specified in the data array + * or in the seriesColors array option on the series. If no colors are defined, the default jqPlot + * series of 16 colors are used. Colors are automatically cycled around again if there are more + * bubbles than colors. + * + * Bubbles are autoscaled by default to fit within the chart area while maintaining + * relative sizes. If the "autoscaleBubbles" option is set to false, the r(adius) values + * in the data array a treated as literal pixel values for the radii of the bubbles. + * + * Properties are passed into the bubble renderer in the rendererOptions object of + * the series options like: + * + * > seriesDefaults: { + * > renderer: $.jqplot.BubbleRenderer, + * > rendererOptions: { + * > bubbleAlpha: 0.7, + * > varyBubbleColors: false + * > } + * > } + * + */ + $.jqplot.BubbleRenderer = function(){ + $.jqplot.LineRenderer.call(this); + }; + + $.jqplot.BubbleRenderer.prototype = new $.jqplot.LineRenderer(); + $.jqplot.BubbleRenderer.prototype.constructor = $.jqplot.BubbleRenderer; + + // called with scope of a series + $.jqplot.BubbleRenderer.prototype.init = function(options, plot) { + // Group: Properties + // + // prop: varyBubbleColors + // True to vary the color of each bubble in this series according to + // the seriesColors array.
