Paint double buffered and reuse the content of the pixmap buffer for some spontaneous repaints that happen when a plot gets unhidden, deiconified or changes the focus. Disabling the cache will improve the performance for incremental paints (using <a class="el" href="class_qwt_plot_curve.html#a7d3ac4d64232a2f7b07557075816831">QwtPlotCurve::draw</a>).</li></ul>
114
Suppress system background repaints and paint it together with the canvas contents. Painting packed might avoid flickering for expensive repaints, when there is a notable gap between painting the background and the plot contents.</li></ul>
