In order to visualize the results, I need some kind of 3D plot or 2D image plot (to visualize matrix values). Having searched for similar topics on the internet and mailing lists I decided to ask here.
What could be the best approach to obtain such plots in GR? Should I try to introduce a new Qt block or use an embedded python block with matplotlib (create a sequence of plots, animation)? I can also do simple postprocessing after collecting the data but live visualization or one with tolerable latency would be most desirable. Maybe I can utilize some of the existing blocks like constellation sink and change the colours of points accordingly to values in the matrix?
Please let me know your thoughts.
