QwtPolarCurve setData()

[Ann24]

Hello!
I'm trying to draw a curve on PolarPlot. I use setData for this. But it requires QwtSerialData<QwtPointPolar> as parametr. Could you show me example how to declare and initiate it?

Same problem here, if someone could help...

this is what I have now:
QwtSeriesData<QwtPointPolar> *datap;
//fill datap with data somehow
curve->setData(datap);
