# OpenGL Accelerated Series Example

The example shows how to enable OpenGL acceleration for QLineSeries and QScatterSeries.

#### Running the Example

To run the example from Qt Creator, open the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example.

#### 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`:

     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.
