AW: 3D plots or image display in GR

[Dobler, Anton]

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

Betreff: 3D plots or image display in GR

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,
Marcin Wachowiak
