Hi, You can check vis3d from https://github.com/gnuradio/gr-inspector/tree/maint-3.7/lib. This gives you a qt surface plot.
I ported this block to 3.8 and it works so far. Still bit buggy but at least it enables 3d "realtime" plotting. cheers ________________________________________ Von: Discuss-gnuradio [[email protected]] im Auftrag von Marcin Wachowiak [[email protected]] Gesendet: Montag, 13.

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. Kind regards, Marcin Wachowiak
