If you're using the full OO interface and creating a figure by making an
instance of Figure(), then you shouldn't need to close the figure by hand.
It should be deleted whenever you delete or replace your instance of
Figure. (If I understand correctly.)

Mike: Yes, I suspect that is the problem. Unfortunately, I've no idea 
how to fix that.
Even if you get beyond that though - I think you are going to run into 
problems with basemap/geos using python 2.6 and numpy 1.2.1. I've been 
waiting for a numpy 1.3 release that fully supports python 2.6 before 
digging into this.

Thank you very much, Jouni. Pyplot.close() seems to have done the
trick. I followed your advice and converted my code to use the OO
interface. But I'm not sure how I close the figure in OO ... Any
pointers? Thanks.

I needed to update my python interpreter to 64-bit recently on my 
mac. I all my needed modules updated fine, including matplotlib, but 
basemap gives me trouble:

P.S. Both matplotlib and basemap are from today's svn.

matplotlib is inconsistent in its treatment of rcParams. Some have 
immediate side effects, others are cached during initialization and 
changing them later has no effect. This is a long standing problem, but 
not one with an easy solution, since the caching, particularly in the 
case of font lookup, is an important optimization.
Personally, I feel that rcParams should be primarily for environmental 
settings, and thus should not be updatable after initialization -- but 
that's only my opinion -- I have heard the opposite argued rather 
convincingly. In my opinion, it is the inconsistency between rcParams 
(or lack of documentation about when they are effective) that is worth 
addressing.
In your particular case, there is an easy non-rcParam alternative -- 
just send text parameters to the title command.

Hi John,
thanks for the heads up:)

I just built mpl on Debian, and the easy test works fine:
$ python -c "import matplotlib ; print matplotlib.__version__"
0.98.5.3
There are some warnings/errors during docs creation, I'll try to debug
them (but I can assure I'll due in few hours/days); if needed I can
provided the (long) build log :)
Cheers,

Dear Tony,
Thank you very much. This is what I was looking for.
It would be nice if it is integrated in the main matpotlib; 
especially if it would be possible to set the projection type in the
matplotlibrc file.

As far as I know, there is no user settable attribute. But something
like below will work.
ax = gca()
title("My title")
ax.titleOffsetTrans._t = (0., 10.0/72.) # x, y offset in points/72.
default is (0., 5/72.)
ax.titleOffsetTrans.invalidate()
draw()
Alternatively, you may use
ax.title.set_y(1.1) # y position of the title in the normalized axes
coordinate. default 1.0

Is there anything like a title pad, similar to the xaxis.LABELPAD?
I'd like to see if the plot would look better with the title a bit higher
off the plot.
Thanks,
Che

Since you call twinx then twiny, you're creating two additional axes, not one.
And I guess this is why labels are drawn twice. You may do
def twin(ax):
 ax2 = ax.figure.add_axes(ax.get_position(True),
 frameon=False)
 ax2.yaxis.tick_right()
 ax2.yaxis.set_label_position('right')
 ax.yaxis.tick_left()
 ax2.xaxis.tick_top()
 ax2.xaxis.set_label_position('top')
 ax.xaxis.tick_bottom()
 return ax2
ax = gca()
ax2 = twin(ax)
ax.scatter([0.4],[0.6])
ax2.scatter([10.],[10.])
draw()
Note that you need to manually adjust the view limits of each axes. If
you use sharex or sharey parameters for the axes, you can share their
view limits (this is how axes is created when twinx and twiny is
called). But then you cannot have different tick locators.
In case you need an axes with a same viewlimit as the original one but
just want to place ticks at different position, you may check my
related post.
