r2808 | Qt Charts 2.1.0 | ||
Miikka Heikkinen
|
r2825 | Performance Improvements | ||
| -------------------- | ||||
| Qt Charts now supports accelerating drawing of line and scatter series with | ||||
| OpenGL. In cases involving large amounts of points, this radically | ||||
| improves performance. For example, a high-end desktop system with a good GPU | ||||
| can draw a series with millions of points at a useful frame rate. | ||||
| See QAbstractSeries::useOpenGL documentation for more information. | ||||
