Hello everybody,
when using this very simple script, I get three subplots which lie on top of a
empty plot covering the whole area of the figure:
from numpy import *
from pylab import *
hold(True)
subplot(311)
subplot(312)
subplot(313)
show()
The result of this code can be viewed here:

If I leave out the line "hold(True)", which could also read "hold(False)", the
underlying plot disappears.
Is there a way to avoid that? Or: Is there a preferred position for the "hold"
command?
Best regards,
Peter Melchior
The pylab hold command sets the hold variable for the current axes. If there is none, it makes one, hence the full-size axes on which your subplots are superimposed. The hold variable determines whether subsequent calls to something like "plot" erase the axes first, or superimpose their drawing on whatever was already there.
What is it you are really trying to do?
