Re: [Matplotlib-users] plots do not scale to size
Hi, I'd very much vote for such a feature, too. It's absolutely not
foolproof currently the way it is :(
What I find weird, too, is that while everthing fits on the canvas for PDF
output, the left side is cropped for PNG.

xlabel makes a label at an indicated physical size. You may not be
explicitly setting those sizes, but they are all defined via defaults
in the matplotlibrc. We try and make mpl do what you tell it to do,
not to try and out-smart you and do what we think you are telling it

Now I definitely support the idea that we should have a *feature* to
auto-adjust the subplots_adjust params and fontsizes so that it just
works more often. But this should be an optional feature so the user
who wants to express their intent clearly will not constantly be
stymied by mpl adjusting the sizes. Michael Droettboom has worked on
it and it is a difficult problem to get right.

I don't mean to bother people with this question again, but has anyone
implemented this auto-adjust feature that John was talking about? It would
be nice not having to adjust matplotlib.rcParams['figure.subplot.left'] (and
friends) in every plot script, or alternatively, through a clever hierarchy
of matplotlibrc files.
By the way: kudos to matplotlib in every other respect!

I am not sure if it is a bug. But, it is usual that such a thing
happens when you are making small figures (like in your case).
Arguably it is a bug, since it is reasonable to expect that when
you set
an xlabel or ylabel (or, say, large yticklabels), it shows up in the
figure. There are at least two problems to solve here: what should
the
user interface be like, and how can it best be implemented?
The user interface question seems difficult to me. If you set the
figure
size to something small (as in this case) and then add labels, should
matplotlib reduce the area available for the plot? Or should it
reduce
the font size of the labels and the tick labels, and perhaps the
amount
of white space between the axes and the labels? Or some combination
of
these?
The implementation question could also be somewhat hairy, since the
bounding box of text objects depends on the backend. If agg and pdf
disagree on the size of a label, is it OK to get different-looking
results in png and pdf?

This _must_ be a bug. Consider the following:
##
import matplotlib
matplotlib.rcParams['figure.figsize'] = [8.85, 3.20]
matplotlib.use('pdf')
from pylab import *
xs = linspace(0, 2 * pi)
ys = sin(xs)
plot(xs, ys)
xlabel(r'$T_{est}$')
ylabel('y axis')
savefig('test')
##
Here, the vertical size is clearly large enough for a label, as it
is a full inch larger than in the previous example. However, the
xlabel is truncated. This _must_ be a bug. When I make a plot, I
would expect that all parts of the plot appear on the plot.
As an example, in Gnuplot, the text just appears in the right
place, but is too large (overlaps the plot, etc). Hence, you see
for yourself that the font size is the problem.
Anyway, it can't be the font size here, as the xlabel was completely
outside the bounding box (I'm not sure of the terminology). To me,
it just looks like a problem with the scaling - the plot looks
perfectly OK in Illustrator, disregarding that it doesn't fit inside
the viewing window.
I'm not an expert, and I certainly don't know how to fix this. But I
do know that other software manages this nicely. Don't get me wrong,
I use matplotlib because I like it - but it should be possible to
fix this problem.
Best regards,
Paul.

Hm, I see. Thanks for an informative answer. I'll dig into my rcParams
and matplotlibrc then...

[Matplotlib-users] plots do not scale to size
Dear all.
When I run the script below, the xlabel and ylabel do not show up. If
I increase the figure size, it all works fine. If I open the file in
Adobe Illustrator, the x and ylabels are both there, but outside the
canvas (or bounding box or whatever it is called). I believe this must
be a bug?
I moved my matplotlibrc file out of its usual location to make sure I
don't have any funny settings which screws things up. I also deleted
the tex cache to avoid any tex-related problems.
Best regards,
Paul.
