\ingroup qtcharts_examples
\brief The example shows how to enable OpenGL acceleration for QLineSeries and QScatterSeries.
\image examples_openglseries.png
To create an OpenGL accelerated series, all you have to do compared to a regular
series is to set QAbstractSeries::useOpenGL property to \c{true}:
\snippet openglseries/main.cpp 1
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.
