Remarks

This event fires just prior to a chart element being drawn, and is raised once for the chart image, and one time for each ChartArea, Legend, Series and DataPoint objects that exist within the chart image (note that this event is not raised for Series and DataPoint objects for 3D charts).

To test what object the event was raised for use the following along with the code snippet above: ChartPicture, ChartArea, Legend, Series, and DataPoint (e.g. the sender object allows the developer to determine what chart element has raised this event).

To see how a chart painting event is implemented see the Custom Drawing Using the Painting Events topic.
