Plotting question

GNU Radio

Hi guys,

I have a question. I have made a python script with some c++ modules.
Everything is working fine, so I’m pretty happy so far. Occasionally
something happens within a .cc file, it doesn’t really matter what
happens.
Whenever this happens I want to make a plot of the event and if it
happens
again I want the plot to be refreshed so that we can keep track of the
event
changing over time. Hope you guys understand what I’m talking about ^^.

So now my question. Is there any way to do this? Should I dive into the
.cc
code and do some sort of plot, not using python? Any other ideas are
very
welcome.

Thanks,
tvb

A quick and dirty fix is to dump the data to a file, then plot the data
offline with python.

I find it convenient to sink the data to a vector_sink and then use
matplotlib to plot the signal.

If you are set on producing a real-time plot from within the c-code, you
can
use opencv. I have tried plplot as well, however I was not successful
in
updating the plot in real-time.
