Qwt 6.0 QwtPlotSpectroCurve dot size

[rolvera]

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.

I have added a setPenWidth method to SVN trunk.

An earlier implementation of QwtPlotSpectroCurve had the option to use symbols, but after some discussion on the mailing list it was obvious, that there are simply too many ways to display the z values ( colors, symbols, symbol sizes ... ).

So I decided to offer a very simple class only demonstrating how to use the QwtPlotSeriesItem template. Be encouraged to implement your own type of curve !
