Bug Description
Hi all. I've been using Pondus for a long time. After upgrading to 18.04 graph stopped working and the graph button is greyed out. If I hover on the button a hint appears, saying "matplotlib not available". I tried to install matplotlib by "apt install" or pip but definitely I am not a Python guy.
Then I tried to start the program from CLI (Kubuntu Konsole and standart Ubuntu terminal). I got the following message at start up:
Exception in thread Thread-1:
Traceback (most recent call last):

from pondus.
