<h3 class="fn" id="useOpenGL-prop"><a name="useOpenGL-prop"></a><span class="name">useOpenGL</span> : <span class="type">bool</span></h3>
<p>Specifies whether or not drawing the series is accelerated by using OpenGL.</p>
<p>Acceleration using OpenGL is supported only for <a href="qlineseries.html">QLineSeries</a> and <a href="qscatterseries.html">QScatterSeries</a>. A line series used as an edge series for <a href="qareaseries.html">QAreaSeries</a> cannot use OpenGL acceleration. When a chart contains any series that are drawn with OpenGL, a transparent QOpenGLWidget is created on top of the chart plot area. The accelerated series are not drawn on the underlying QGraphicsView, but are instead drawn on the created QOpenGLWidget.</p>
<p>Performance gained from using OpenGL to accelerate series drawing depends on the underlying hardware, but in most cases it is significant. For example, on a standard desktop computer, enabling OpenGL acceleration for a series typically allows rendering at least a hundred times more points without reduction on the frame rate. Chart size also has less effect on the frame rate.</p>
<p>The OpenGL acceleration of series drawing is meant for use cases that need fast drawing of large numbers of points. It is optimized for efficiency, and therefore the series using it lack support for many features available to non-accelerated series:</p>
<ul>
<li>Series animations are not supported for accelerated series.</li>
<li>Point labels are not supported for accelerated series.</li>
<li>Pen styles and marker shapes are ignored for accelerated series. Only solid lines and plain scatter dots are supported. The scatter dots may be circular or rectangular, depending on the underlying graphics hardware and drivers.</li>
<li>Polar charts do not support accelerated series.</li>
<li>Enabling chart drop shadow or using transparent chart background color is not recommended when using accelerated series, as that can slow the frame rate down significantly.</li>
</ul>
<p>These additional restrictions stem from the fact that the accelerated series is drawn on a separate widget on top of the chart:</p>
<ul>
<li>If you draw any graphics items on top of a chart containing an accelerated series, the accelerated series is drawn over those items.</li>
<li>To enable QOpenGLWidget to be partially transparent, it needs to be stacked on top of all other widgets. This means you cannot have other widgets partially covering the chart when using accelerated series.</li>
<li>Accelerated series are not supported for use cases where the graphics scene has more than one graphics view attached to it.</li>
<li>Accelerated series are not supported for use cases where the chart has non-default geometry. For example, adding transforms to the graphics view causes the accelerated series to be drawn in an incorrect position related to the chart.</li>
</ul>
