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.
