| Qt Charts 2.1.0 |
| |
| 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. |
| |
| New features |
| ------------ |
| - Added support for QAbstractSeries::useOpenGL property |
| - Added possibility to set labels position for QCategoryAxis |
| - Added reverse axis support |
| - Added support for minor ticks to value axis |
| - Added support for bar series value label angle |
| - Added QXYSeries::replace(QVector<QPointF> points) overload |
| - Added QXYSeries::pointsVector() to get series points as a QVector. |
| - Added possibility to set duration and easing curve for chart animation |
| - Added a method to remove more than one point to QXYSeries |
| - Added option to set labels clipping |
| - Added grid color property for value axis |
| - Added mapToPosition and mapToValue methods to ChartView |
| - Added zooming functions to ChartView to correspond the ones available for QChart |
| - Added changed signals to scatter series marker size and shape properties |
| |

| - Fixed assert failure due to wrong default axis for DeclarativeChart |
| - Fixed XYSeries point label drawing |
