Class IlvStairChartRenderer

java.lang.Object

ilog.views.chart.IlvChartRenderer

ilog.views.chart.renderer.IlvCompositeChartRenderer

ilog.views.chart.renderer.IlvSimpleCompositeChartRenderer

ilog.views.chart.renderer.IlvPolylineChartRenderer

ilog.views.chart.renderer.IlvStairChartRenderer

public class IlvStairChartRenderer
extends IlvPolylineChartRenderer

A renderer displaying stairs. This renderer creates an instance of IlvSingleStairRenderer for every data set in the connected data source.

For a stair chart, the displayed value at a point x₀ within the data range is computed by looking up the data set point with the largest x <= x₀ and taking its value.

Note: This renderer only works with data sets whose x-series are sorted in ascending order (see IlvDataSet#isXValuesSorted). To sort a data set into ascending x order, you can use the class IlvXSortedDataSet.

Note: This renderer does not work in 3-D mode in the STACKED or SUMMED modes. This is a limitation.

The following figure shows an example of an IlvStairChartRenderer.

CSS example:

ilvStairChartRenderer {
class : "ilog.views.chart.renderer.IlvStairChartRenderer";
annotation : "@#ilvDataLabelAnnotation";
autoTransparency : "false";
marker : "CIRCLE";
markerSize : "2";
mode : "SUPERIMPOSED";
name : "<value>";
stacked100Percent : "false";
stackedByIndex : "false";
styles[0] : "@#ilvStyle1";
styles[1] : "@#ilvStyle2";
visible : "false";
visibleInLegend : "false";
YAxisIdx : "2";
}
