I was able to find a way to zoom centred on the mouse. What I did was make use of the QChart::plotArea() function. With that function by using ChartView::wheelEvent(), I could get where in the chart the zoom is happening. I then did some math and set the new zoom for the chart by adjusting the range for the chart's x and y axis.
Fortunately I could do this with the existing API. It would be nice if there was a cleaner API for doing this though. -- Lorne Sturtevant Sum Ergo Cogito _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
