I've recently upgraded to Qwt 6.0.0 rc4, and I am using a QwtPlotSpectroCurve to overlay realtime color encoded data over a QwtPlotCurve in black. The problem is the dot size for the QwtPlotSpectroCurve is too small and is not showing the color well when there are small sample rates.
Is there a way to increase the dot size? It seems what I really want is a scatter plot with symbols, but it doesn't seem to be supported.
Any advice, would be appreciated.
