Widget for data plotting

[Benjamin]

Hi all,

I need to start working on a widget that will plot 2D data. What I basicly have is 210 dots that I need to plot and to detect peak in that graph.

I am wondering if someone can pont me to some examples that I can use to understand drawing in Qt4.


Tnx,
Benjamin

Qwt is LGPL with a few exceptions, so yes, it can be used in commercial applications. More info: Qwt License, Version 1.0 (http://qwt.sourceforge.net/qwtlicense.html)
