Step Displayers in a Cartesian Chart and in a Polar Chart
We can use the step displayer displaying the red steps as an example. We can create this displayer by using the following code:
IlvStepChartDisplayer* displayer = new IlvStepChartDisplayer();
displayer->setForeground(dpy->getColor("red"));
Note: The Drawn Filled property has no meaning for the step displayer. The steps are simply drawn with the foreground color of the defined palette.
