In the example as you move your mouse around the screen it shows you the X and Y values through the modified QwtPlotZoomer class. Is there a way to get the Z value as well? I have setup an example using QwtPlotSpectrogram with QwtRasterData and it works well but I am a little stumped as to how to get the Z value as well as the X and Y as I move my mouse around.
Thanks for your time guys
