Scatter Displayers in a Cartesian Chart and in a Polar Chart
We can use the scatter displayer displaying the blue triangles as an example. We can create this displayer by using the following code:
IlvScatterChartDisplayer* displayer = new IlvScatterChartDisplayer(IlvMarkerFilledTriangle, IlvDefaultMarkerSize); displayer->setForeground(dpy->getColor("blue")); |
Note: The Drawn Filled property has no meaning for a scatter displayer. The markers are simply drawn with the foreground color of the defined palette. |
