Hi @ all,

First of all, im new to Qt, Qwt and Programming.
So my Problem is:

I have a Matrix which i have uploadet to the Qwt rasterview example. I have also implemented a QwtPlotPicker.
Now with the QwtPlotPicker i am able to get the Position values by draging a Line from Point A to B but instead i would like to get the Matrix intensity Values of the Colormap from A to B and Plot them with QwtPlotCurve.

Any suggestions for me how to handle this?

Thx for your Support.
