Enabling OpenGL Acceleration▲

To create an OpenGL accelerated series, all you have to do compared to a regular series is to set QAbstractSeries::useOpenGL property to true:

 
Sélectionnez
series->setUseOpenGL(true);

This makes the chart to instantiate a transparent QOpenGLWidget that is used to draw the accelerated series on top of the chart.

The OpenGL acceleration is only supported for QLineSeries and QScatterSeries.
