thanx in advance…
Did you transform the painter in any way? Are you using widget local coordinates? Have you considered any border you have drawn?
C++ GUI Programming with Qt 4 (First Edition), which is available for free at the link found in my previous post, has a chapter about custom widgets using the example of a plot widget, which supports zooming and scaling.
I also want to plot graphs, but I don’t want to make a new program because there are already good ones and I don’t have the level to make something better.
The approach I will probably take is using SciDAVis [scidavis.sourceforge.net], which is written in Qt and has a plugin interface.
I let you know this in case it’s useful, but I suppose you want to write your own.
Sorry, I thought it was a good idea, but I’ve seen that SciDAVis plugin capabilities can be found only in the bleeding edge version (0.3.0). Here you can see that version’s classes [scidavis.sourceforge.net].

It isn’t QWT and seems very customizable.
