Philipp,
Thanks! That's the reason indeed!
The workarounds do work but with pitfalls. With xstring() the label
moves around when zooming in or out, and xlabel takes too much space, in
fact saving space was the reason to place it only on the last plot.
Probably it would be possible to adapt
Hi Federico,
my best guess: In your example only subplot(4,1,4) gets the x_label
Since this needs space, the diagram is smaller.
Workaround:create label for x-axis via xstring
Or:
Assign a x_label for each subplot, but hide it.
This will assign "space" for the label, but it won't be
