Hi all,

I am trying to use qwt library to create my contour plot and I notice somebody on the forum has done that also but I couldn't quite figure out how to do it yet looking at the spectrogram example. I'd appreciate all help regarding this and please pardon my stupidity.

Basically what I have is a set of points in the format of (x, y, v) with x, y being the coordinates of the points and v is the value at the point. Do i then need to apply some sort of interpolation algorithm to find the points in between those points because certainly the points that I have don't fill up the entire display viewport, or this has been done inside the qwt library? Also, where do I need to enter my points?

Thank you so much for all your help.
