Hello all, I would like to optimise plotting performance so I have tried to enable openGL for the plot.
ui->spectrumPlot->setOpenGl(true);
The problem is that everything in plot is double size now. I have tried to use setBufferDevicePixelRatio() method but it does not seem to have any effect. I am building QCustomPlot and my application with Qt 6.7.3.
