Jérôme Duriez proposed the following answer:
Hi,

>From the source code [1], the behavior seems to be the one of [2] (?
hoping I did not step into a trap of different Python modules). There
seems indeed to be an automatic modification of the length which could
trouble you. Behavior could be different though, try maybe to pass
additional arguments e.g.

post2d.plot([...], scale = aConstantValueThatSuitsYou)
