Displaying intensity values of Spectrogram in trackertext.

hi,

I wan't to display the intensity value of a pixel (in the Spectrogram example) along with the x and y co-ordinates in the qwtplotzoomer trackertext. how do i do it . :(

thanks.

Overload QwtPlotZoomer::trackerText. Here you need to have access to your data object, that can give you the value for the current position.
