Enabling OpenGL Acceleration#

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

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.

Note

The OpenGL acceleration is only supported for QLineSeries and QScatterSeries .
