Hi Marcus,
Thank you for your patience with my CtrlPort Performance Monitor problems. I
have been distracted by other projects and finally had time to try your
suggestion.

Here is the terminal output from running gr-perf-monitorx:
address@hidden:~/gnuradio/prefix/perfmon$ gr-perf-monitorx vmware 46263
QPaintDevice: Cannot destroy paint device that is being painted
Traceback (most recent call last):
File
"/home/jim/.local/lib/python2.7/site-packages/matplotlib/backends/backend_qt5agg.py",
line 72, in paintEvent
painter.drawImage(origin / self._dpi_ratio, qimage)

"/home/jim/.local/lib/python2.7/site-packages/matplotlib/backends/backend_qt5.py",
line 273, in _dpi_ratio
return self.devicePixelRatio() or 1
RuntimeError: wrapped C/C++ object of type FigureCanvasQTAgg has been deleted
Segmentation fault (core dumped)
Does this give you any ideas about what is causing the blank Performance
Monitor graph display?
Regards,
Jim
