[Qt-interest] What to use as a base class for histogram classes?

[James Matta]

I am working on writing a data analysis tool for my research and I need to
be able to display 1D and 2D histograms (see attachments for examples).
Users need to be able to do things like click within the histogram and have
the position recorded (so that they can give initial values for peak fits,
identify channel number/ number of counts etc more finely than the scale
might give, highlight regions of interest, etc.)

My first thought was to subclass out of QPainter or QPaintDevice or one of
their subclasses; but, I am uncertain of whether or not this is the best
choice, or even if it is a good choice. I would appreciate any advice that
you might have on the subject.

Thanks in advance.

Cheers,
