Thread: [matplotlib-devel] subplot

Hi. I just installed the newest version of matplotlib (0.82), and 
discovered all my subplots were ending on top of each other. After going 
through my code and verifying everything looked okay, I tried a simple:
subplot(2, 1, 1); plot(range(0, 10)); subplot(2, 2, 2); plot(range(0, 10))
and still only got one subplot. I went to the matplotlib code, and after 
some prodding, discovered that all the keys for the _seen map were 
exactly the same. Going to the _make_key function revealed that my use 
of subplot (i.e. three seperate arguments), was not working. Here is a 
fix that seems to work for me:
(int _make_key function):
 if iterable(args[0]):
 key = tuple(args[0]), tuple( fixitems(kwargs.items()))
## NEW
 elif len(args) > 1:
 key = args, tuple( fixitems(kwargs.items()))
## \NEW
 else:
 key = args[0], tuple(fixitems( kwargs.items()))

Abe,
That bug has been fixed in CVS; like you, I tripped over it in 0.82 and 
tracked it down--but someone else had already fixed it. A workaround, 
if you don't want to install from CVS, is to use the old subplot(211) 
form instead of subplot(2,1,1).

That's good to know. I tried googling it, but I guess I should've also 
checked CVS as well. I'm sure it's better than my hack anyways -- just 
good to have my scripts working again. I tend to prefer the subplot(w, 
h, n) since most of my plotting is automated, and it's more of a pain to 
have to convert the parameters to a string first, etc.
