Hello,

I am fairly new to Qt and Qwt. I am trying to plot my data that is in a 2d matrix onto the polar spectrogram plot, but i have no idea how the plot is suppose to be setup to accept that kind of data and if there is a proper way to feed that data to the plot. I have been trying to read the documentation but i am struggling to follow it.

I was messing around and was able to create a QwtMatrixRasterData object that has dummy data stored in a QVector<double>, but was not able to get it to successfully display any of the data i feed to the plot using the setdata() function.

I don't know if I was going in the right direction, but any help on this would be greatly appreciated and thank you in advance for any help given.
