    Default Customizing QwtPlotCurve and QwtPolarCurve

    Hello!

    I'ld like to know how one could customize a QwtPlotCurve or a QwtPolarCurve to show something 'beyond' merely a simple curve. Particularly, I'ld like to know how to make QwtPolarCurve displays an arrow as phasor graphs normally do. I thought about reimplementing the virtual "drawCurve" method, but I couldn't do it in a way that would work. Could somebody please lend me a hand on this?


    Thanks,

    Momergil
    May the Lord be with you. Always.

    Maybe you can implement a plot item. See...

    Can you post an example how that looks like?
