Interactive graph in Qt
I want to make such an interactive graph using Qt and C ++: http://jsxgraph.uni-bayreuth.de/wiki/index.php/Cubic_spline_interpolation
Any hints on how to do this?
EDIT: Ok, I've already tried my hands on the QGraphicsView class and qwt library. However, I don't find an easy way to represent interactivity. Is there an easy way to do this?
