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