Dear all,
I have to following problem: after having installed the package (from
GitHub) I have the possibility of choosing PyQtGraph in rqt_plot, but if i
select it nothing changes, and when I check again in the setting, the
MatPlot is always selected. I use Ubuntu 18.04 with ros Melodic.
I don't know if it is an useful piece of information, but if i run: python
-m pyqtgraph.examples (as suggested in the PYQtGraph page) the result is
the following.
agotelli@ProBook:~$ python -m pyqtgraph.examples
Traceback (most recent call last):
File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main

super().__init__(*args, **kwargs)

Thank you all for the help in advance.
