Hi,

sorry, I should have mentioned it explicitely. I had checked for
matplotlib, it was automaticalliy installed

---------
root at debian:# apt list --installed |grep matplot

WARNING: apt does not have a stable CLI interface. Use with caution in
scripts.

python-matplotlib2-data/stable,stable,now 2.2.3-6 all
[Installiert,automatisch]
python-matplotlib/stable,now 2.2.3-6 amd64  [Installiert,automatisch]
-------------

greetings
Susanne
