QwtPolarPlot as radar display. Plotting in realtime.

[crooveck]

Hello
I need to implement something similar to military radar display.
I have a program that generates many vector's of doubles (std::vector<double>) and stores them in boost::circular_buffer. Now I need to implement a polar plot to display it in real time, as they are pushed into the buffer.

I've also found QwtPolar that ideally suits my needs (spectrogram version). But it needs QwtRasterData on input and create the plot.
My question is: is there a way to implement real time radar display using qwtpolar (or other qwt/qt widgets).
