    Default QwtPolar: Plot using a 2-dimensional array

    Three days ago I posted the same question in "Newbie", I didn't get any reply.
    Perhaps it was the wrong forum, so I try it here again.
    I am happy with any good idea!

    Please help with an example how to plot a curve using QwtPolar when data is stored in a two-dimensional array.
    It's really urgent and I hope my question is not too primitive!


    Thanks a lot, hgstoehr

    See http://qwtpolar.sourceforge.net/clas...b95be73931d84e

    Derive from QwtSeriesData< QwtPointPolar > returning the points from your 2D array - or use a QVector<QwtPointPolar> ( instead of your array ) in combination with QwtArraySeriesData< QwtPointPolar >.
