getting value of clicked point wxFreeChart

Question

Hello,

Does anyone know how can I get value of clicked point on wxFreeChart plot ?

Thanks for any hint.

In documentation (http://wxcode.sourceforge.net/docs/freechart/)

there is soemthing like:

bool AxisPlot::ToDataCoords (   size_t  nData,
wxDC &  dc,
wxRect  rc,
wxCoord     gx,
wxCoord     gy,
double *    x,
double *    y    
)

But I dont know how can I get rc and other parameters.
