OK, so I used the above instead that obscure backend_gtk3agg hack.
I am still not sure what to do about NavigationToolbar2GTKAgg part -- will
that work out of the box?
I appreciate your effort, but generic answers on how to work in python are
not helpful.
I am not in python business, and I am not going to rewrite the program --
it is not mine to begin with.
So now I get the next error, exactly the same as I have reported in the
original report:
File "/usr/lib/python2.7/dist-packages/matplotlib/pyplot.py", line 115, in
<module>
_backend_mod, new_figure_manager, draw_if_interactive, _show =

line 62, in pylab_setup

line 34, in <module>
raise ImportError("The Gtk3 backend requires PyGObject or pgi")
ImportError: The Gtk3 backend requires PyGObject or pgi
What is this about?
It would be so much better if one would read the report in full.
Note that python-gobject-xxx and python-gi-xxx are installed, see the
original report.
