I think I might have found the problem:

Thank you for your reply.
I tried changing the figsize, but it didn't work. I think what I might need to do is to change the actual lenght of the axis.
I have a picture of the results, changing the figsize, but unfortunately I don't know how to put it here...

Hello people,

I am working on modeling a groundwater problem with jupyter notebook.
The model is working just fine, but I have a problem with my plot. Since the model domain has a length of 2500m and only a width of 2m the plot appears to be very thin.
Now I want to change the scaling of my x-axis ...
