Just wondering: you wouldn't happen to plot a space character by itself, by
any chance ? I remmbr running into something similar (the dvifile not being

Check the "aspect" keyword of your image, and try to set it to 'auto'.

Folks,
I've just noticed that in order to get the size of a figure in inches, one can
use:
>>> fig.get_size_inches()
However, the corresponding 'set' method is
>>>fig.set_figsize_inches()
Is this intentional ? Wouldn't it be better to keep the set/get methods
consistent ?
Thx for your insight

Update numpy. Or matplotlib. Or in matplotlib/dates.py, change line 155 from

to
remainder = float(x) - ix

Glen,
Funny, I ran into exactly the same problem earlier that week. My guess is that
you use numpy, right ? 0.9.8 ? On a 64b machine ?
If that's the case, you should have the same problem with divmod and numpy
each time you use float64 as dtype: each element is a float64scalar that

Try to set the "_autoscale" parameter of your current 'axes' to False. That
way, you should avoid any inopportune rescaling. For the image, try

Assuming you have a plot (not an image):

or gca.set_xlim(360,0)

Please transform your array in a MaskedArray.

That's what I like in matplotlib: no matter how hard you try, there's always a

Sweet ! Thanks a lot !
And following your advice, I came up with the following solution to my problem
(forcing the mantissa to multiple of 3, with a given number of decimals).
Folks,
I need your wisdom about ticks labels on ordinates for large numbers (>1e4).
The default behavior I have (0.87.4) is to display tick labels as "%.1f", and
write a string "x1e+..." above the top left corner of the current axes.
- When using "yaxis.tick_right()", the "x1e..." string stays a
