Compiled Yade plot error in batch mode on Ubuntu 18.04

Hello, how do you expect to see plots in batch mode? I mean, it makes
little sense to pop up an arbitrary number of graphical windows, expecting
one to watch and close them while the batch proceeds. What do you really
need?

Oh wait, isn't it just a change in different matplotlib versions? I've seen
such things. Try with a simple pyplot to confirm it is related to yade?

Sorry for the confusion. I meant that when I open the progress via web browser (localhost:9080) [1].

On Ubuntu 16.04 the version of matplotlib is 1.5.1 and on Ubuntu 18.04 it is 2.1.1, so it is a change in versions.
Could you lend me some instructions about the confirm by simple pyplot, please?
If it is the problem because of the different versions, is there a workaround or I have to force install the older version?

Thanks,
Daniel

Thanks Bruno Chareyre, that solved my question.
