Hi David and Ben and everybody reading along,
Apparently I did not phrase my question too well.
To clarify:
I would like to have some 'subplots' with a width proportional to
the amount of (equally spaced) data points.
It seems to me that gridspec (http://matplotlib.org/users/gridspec.html)

Hi,
I've lost touch with the state of mpl and starting to use it again. Apparently
some of the gallery examples in 3D aren't working, but I think I found a
workaround.
However, is there a way to get 3D bar charts with semilog style (e.g.
logarithmic x-axis?)
Right now, I have:

Honestly, I neglected my mpl skills lately, so I don't know whether docs
on this topic are available, but I couldn't find them either.
I would like to create a forest plot using horizontal errorbars.
Currently my marker is simply 'kd' in pylab.errorbar, where 'd' is
similar to LaTeX's

live without it.

I won't find the time to implement this.

Hi,
Is there a way to somehow squeeze two datasets with two different color
maps into one pcolormesh? Say one dataset occupies one triangle (e. g.
numpy.triu(dataset1, 1)) and the second dataset a different area (e. g.
numpy.tril(dataset2, -1)) and then paste the two datasets in one

Hi,
Does anyone provide a script / patch to create zap symbols (e.g. like

Thanks Darren,
Then, I guess, the easiest solution is to either use to set all tick
labels manually or to just use serif fonts ;-).

I'd like to have all sub-fonts (labels, tick labels, text) sans-serif

Hi,
I'm plotting 2D-ndarrays with pylab.pcolor(). The data contain masked
values and it can happen that entire rows or columns hold only masked
values. Is there a build-in way to omitted such rows/columns? Currently
I'm removing the labels in x and y and the row/columns by hand.

Hi,
Let me reformulate my question: Is there a way to put ticklabels not
beside, but between ticks (centered between)?

Hi,
Sorry, if this has been brought up before, but I missed a while reading

When I updated my system lately, I also installed the current version of

LineCollection now to get my horizontal lines. Well, I didn't figure

Am I right if I presume that line No. 4 in the second listing in

the example plot would look different.

Hoi,
There is still MPL's polyfit function and I have to admit that Steve
Schmerler's solution looks better that mine, but I've pasted a quick
dirty solution here:

It shows the use of polyfit as well as (almost) Steve's approach.

Hoi Peter,
$\rm{some label text} (\mu V)$ becomes somelabeltext\muV
You could try
r$\rm{some\ label\ text} (\mu V)$
instead. (Note the backslashes and the 'raw' r in front of the string.)
This way the string should be interpreted fine. You can use the '\ ' to
force a space, but whether it's

it's width fixed.

For some plot I'd like to display a dotted line (style = 'k.-') with an error

Of course, I could produce a slice like mydata[::jumper] and plot these above

I'm producing eps files using matplotlib (current version) on a linux box with

or try to embed it in a latex document there is no problem.
Now I've copied these files on a Windows machine and I opened them in
Hi,
No stupid question at all! I don't really understand your question, but it
sounds to me like a scatter plot is what you want. In that case, just have a
look at the scatter plot demos on the web page (- screenshots) or in the
example files.

This makes circles filled with white. If you want circles that don't

As for the fonts, yes, you can control this with rc.
Sure, but what about the latex rendered parts? (I wonder whether it actually
matters, but I'd like to be sure, because there so little time left ...)

Hi,
I'd like to plot experimental data points with fitted data through it. This
time best would be to plot hollow circles for the experimental data. Pretty
much like literal 'o's (except, of course, that passing 'o' results in thick
circles).
Is this possible somehow?

As for the preview header, I suspect there arte 3rd part tools that
can do this (ImageMagick?). We should be able to do it ourself with
agg, but it would require someone to dig in and figure out the spec.
