Re: [Discuss-gnuradio] Plot I vs Q vs Time

Hi Chris,

not in-tree, no, but have a look at the pretty visualization Gerald Baier's gr_channelsounder produces, maybe it's what you're after.

Other than that, there's pyqtgraph, with which you can generate dynamic 3D plots with relative ease; Tim O'Shea has gr-pyqt , which uses that, but I don't think for 3D graphs (haven't looked in a while); I think any code additions to that are welcome (it's FOSS, after all), and you can possibly just take one of the sinks (the ctime_plot.py would be my starting point). Note that gr-pyqt deals with messages containing sample packets (instead of streams); while this might mean you need to "packetize" your sample stream into messages first, I personally think this is the way to go in the future, anyway.

Best regards,
Marcus

Update: After a quick discuss with another dev, I am after that third dimension view so the regular time or constellation sinks are not what I need. The time sink has I and Q on the same Y axis, with time in X.

 

I was hoping there was an existing edit to the standard wx or qt time sink to see I vs Q vs Time in x, y, and z.

 

Thanks! C
