%ZEN.SVGComponent.treeMapChart

Class %ZEN.SVGComponent.treeMapChart Extends chart [ Deprecated, System = 3 ]

This is an SVG chart component that displays a tree map.
A tree map displays a series of values as a set of rectangles. The area of each rectangle is proportional to its value. Negative values are ignored.

Properties​

showPercentage​

Property showPercentage As %ZEN.Datatype.boolean [ InitialExpression = 1 ];

If true, percentage values (rounded to 2 decimal places integer) are displayed as part of the label for each box.

ongetColorScaleData​

Property ongetColorScaleData As %ZEN.Datatype.eventHandler;

ongetColorScaleData event handler: This event handler, if defined, is called by the chart to compute the color scale for a given data item. It should match the format of ongetData, returning corresponding color scale values for each data point returned by ongetData. For example, to scale the colors of each data point according to the "value" of that data point itself, set this property to the same event handler as ongetData. The scaled colors will be using the first color defined in seriesColorScheme, optionally overridden by seriesColors.
