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

I guess I got your point (I'm not familiar with using plot items this way, so it was difficult to remember of this option :) )Quote:

Added after 42 minutes:
Well, I did managed to reimplement draw() and create a custom arrow. The problem now is: how should I connect this item with a QwtPolarCurve, such as when the curve appears, it draws the item at its corner making the arrow figure? Reimplementing drawCurve and draw from QwtPolarCurve is only giving me crashes \o/
Well time have passed and I still haven't found any solution to this problem. Anyone could help?
Can you post an example how that looks like?Quote:
