3 Performance Improvements
4 --------------------
5 Qt Charts now supports accelerating drawing of line and scatter series with
6 OpenGL. In cases involving large amounts of points, this radically
7 improves performance. For example, a high-end desktop system with a good GPU
8 can draw a series with millions of points at a useful frame rate.
9 See QAbstractSeries::useOpenGL documentation for more information.
