I need to know how to make charts/graphs in Blackberry 10 Cascades Beta 3 SDK, QML, Qt, C++. If anyone can show me an example or point me to something that shows me how to do this, it would be much appreciated.

Update The Qt Company will release QtCharts in 5.7 under GPL http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
