Oscilloscope does not display information well

GNU Radio

Hi everyone,

I am using gnuradio 3.2 on OSX and I’ve noticed that the oscilloscope
script
“usrp_oscope.py” does not display the axes of the scope output and
ch1, ch2, trig, etc. tabs don’t work as they should.

I was wondering if anyone knows what might be wrong here - any input
would be greatly appreciated.

Thanks,
Demijan

this scope, right? http://www.joshknows.com/images/wxgui/wxgui_scope.png

it could be one of these issues:

  1. cpu is over drawn, not enough left for the ui
  2. opengl problems

if you cant resolve that, you can try disabling the gl sinks (so it uses
plain wx plotter). set style=nongl

Yes, that the application that I have in mind. My oscope GUI looks
like this, for some reason:

Any pointers as to how I can deal with the possible opengl problems? I
tried the
third suggestion and it didn’t work very well.

Thanks,
