Paul, et al.:

   Changing "underline " to "underline" fixed the problem. Now I have some
legacy database connection issues since pysqlite3 is now included with
python. Ergo, no more matplotlib complaints! (I suppose that removing the
kidsd.* font had nothing to do with it, but I don't use that font in any
case.)

Thanks very much,

Rich

Paul,

   Yes, it was a nice, long, relaxing visit. I go to the dental school at the
health sciences university; costs ~ 1/3rd less than a private dentist,
top-notch care, and the latest techniques when necessary.

   Oops! That was a while ago. I'm rather overwhelmed with client work, but
will see if I still have an IRC tool available on the system; I removed
bitchx a while ago.

I am hoping to have a general discussion about font choices other
matplotlib users make when the figure will be seen by someone other
than yourself. Generally speaking, my figures go in to technical
memos, automatically generated reports, and on rare occasion a web
page.

For memos (created in your standard word processor at a 12 pt font), I
tend to use a 10 pt font on everything (tick labels, axis labels,
legend entries, etc). At work we use Myriad Pro (a sans serif font)
for all of our maps, which works well with plots since it goes well
with matplotlib's stix-sans math text option.

My automatically generated reports are always compiled using Latex
with the fourier package, which uses the utopia fonts (serif). So in
matplotlib I always set usetex to True and add the
\usepackage{fourier} command since that provides a seamless text and
math-text font with support for the upright Greek letter mu. The
upright mu is crucial for environmental data since the quantities that
I'm plotting are typically in micrograms per liter or kilogram.

For static images in webpages and presentations, I go back to my
sans-serif configuration and bump up the fonts as needed.

Also, my axes and tick label markers are 0.5 pt wide, though I'll bump
that up to 1.0 if a very large figure is needed.

Cheers,
-paul

Well, I hope the dentist trip was more of a success :) Don't worry
about it - it's become kind of a fun challenge now.

I see you sent this just a few minutes ago - let's try to figure this
out interactively via IRC on #matplotlib channel on freenode. If you
don't have an IRC client handy, you can just use this web-based one.

   Sigh. I'm sure it's as frustrating for you as it is for me.

Dylan,

It is a feature I have worked on a bit, but haven't fully completed.  Check
out this thread:

http://comments.gmane.org/gmane.comp.python.matplotlib.general/27415

I should see if I can rebase that branch on the updates I have made to
mplot3d since then.
I hope this helps!

Matplotlib users,

Hello, I am currently trying to create a 3D plot of a ships hull using the
plot_surface command in an instance of Axes3d.  The default aspect ratio
for the surface_plot is a cube which, obviously, makes a silly looking
ship.  The x-axis ranges from 0-150, the yaxis ranges from -10,10 and the
z-axis ranges from 0-10.  I want to retain the aspect ratios of those data
sets in the plot (to get the long, slender ship-looking surface).  I can
get the z and x axes to match up by doing something like:

aspect = (len(xaxis)/len(zaxis))**-1
ax.set_aspect(aspect,'datalim')

However, I can not find a way to get different aspect ratios between axis
to get each one in scale with the three data sets.  Is there a way to do
this currently with the Axes3d objects?

Thank you for your help,
Dylan
