Accelerating lineseries with OpenGL...
Accelerating lineseries with OpenGL Added support for QAbstractSeries::useOpenGL property. When true, the series in question is drawn on a separate offscreen buffer using OpenGL and then superimposed on the chart. Currently this property is only supported for line and scatter series.
