Re: 3D plots or image display in GR

[Martin Braun]

Marcin,

gr-specest (https://github.com/kit-cel/gr-specest/) has some cyclostationary code, as well as some matplotlib-based plotting thereof. The code was written in the Py2k era and might be out-of-date. But it might be an inspiration!

Hello,

I would like to experiment with some cyclostationary signal detection in GNU Radio.

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,
