I'm actually testing your component for a client software.I'm doing a Gantt chart and i'd like to know if we can customize a time entry to put a picture or a geometric shape into.. thanks for you help
custom drawing of such things is possible if you handle the FillSceneGraph or ChartDrawItem events.
The ChartDrawItem event is raised for all Primitives added to the SceneGraph, so you can do things like change the PaintElement of one Box primitive to display an image Background.
The FillSceneGraph event is raised each time the chart is painted, so you can do things like loop through the SceneGraph, find all your Box primitives, and overlay Polygon or ChartImage primitives at the desired locations.
