22.9. Using CSIM with matrix plots

Note

This feature was added in v3.1.1p

In the same was as most other plot types matrix plots also supports the usage of Client Side Image Maps. (See Chapter 10 for a full description on the usage of CSIM in general the library.)

The possible hotspot areas in a matrix graph are:

The following example shows how to add both label and data CSIM. As usual the graph must be stroked with a call to MatrixGraph::StrokeCSIM() when using CSIM functionality.
