You'll need to do one of:

1. upgrade to matplotlib v1.1.0
2. apply the patch at https://github.com/matplotlib/matplotlib/commit/708c451
3. edit your pdftex.map file to not specify multiple encodings for one font;
   in one case, the culprit was URWBookmanL-DemiBold aka pbkdo8y

I recommend upgrading, but if you're comfortable editing TeX
configuration files, number 3 is the easiest workaround.

Dear Ben Root,

I have made a pull request of matplotlib on github, and I put my venn 
function on 
https://github.com/icetime/matplotlib/blob/master/lib/matplotlib/venn.py. However, 
I'm not sure it is the right place venn.py should go.

This is my first time try to contribute to an open source project. Could 
someone please help review the code? Any comments will be greatly 
appreciated.Thanks.

Regards,
Jianfeng

Hello all,

I'm using matplotlib 1.0.1 with python 2.7.2 (also 2.6.7) on Mac OSX 10.6.8 installed via fink. I'm not sure at what point using pdf output using Agg stopped working. I can still use eps output, so I'm not sure what is going wrong. Here is the error I get:

Do I perhaps need to rebuild matplotlib because of a LaTeX update?

You can use a proxy artist:

I need to use a small linewidth in my plot but the color is still very
clear. However in the legend the small, thin straight line makes it
difficult to tell the color. Is there a way to make the linewidth larger
just in the legend but not on the plot?

Hello all,

I would like to make small figures (about 3" wide) so that they are exactly
the right size for a LaTeX document I am preparing.  This should be
straightforward, but I fear I am running into inherent limitations in the
matplotlib design.

The particular problem is that the dash spacing for dashed lines seems to
be fixed to a certain number of points.  This looks fine for default figure
sizes, but in a small figure, the dash length becomes comparable to the
width of histogram bars I'm producing, so the output just looks like a
series of unrelated scribbles rather than a coherent histogram.

I've produced a short program below which gives a minimal demonstration of
the problem.

Is there some way to change the length of dashes?

Currently, I am hacking together a solution which involves making large
figures with huge font sizes, but I would much rather be able to match font
sizes exactly by making the figure the right size in the first place.

Many thanks,
Jeff

I have made a pull request to change gen_gallery.py to generate a gallery
page that breaks down the examples by sub directories.

https://github.com/matplotlib/matplotlib/pull/714

The idea would be that people can suggest new directories, get rid of
poorly named directories, and move around existing files.  The
gen_gallery.py would only need to update its list of sub-directories.
Also, examples/index.rst would also need to be updated, but maybe we can
get that page auto-generated as well?

Cheers!

One way is to install mpl from git master.  The ScalarFormatter handles 
this situation better now:

In [15]: print '\n'.join([tl.get_text() for tl in ax.get_yticklabels()])
$\mathdefault{0.0000052300}$
$\mathdefault{0.0000052305}$
$\mathdefault{0.0000052310}$
$\mathdefault{0.0000052315}$
$\mathdefault{0.0000052320}$
$\mathdefault{0.0000052325}$
$\mathdefault{0.0000052330}$
$\mathdefault{0.0000052335}$
$\mathdefault{0.0000052340}$
$\mathdefault{0.0000052345}$

Just a suggestion. All these ideas sounds like a "google code-in" task.

http://code.google.com/intl/pt-BR/opensource/gci/2010-11/

I do not know if "Matplotlib" participated in the past, if not take a
look of last years sympy task list:
https://github.com/sympy/sympy/wiki/GCI-2011-Task-list

If the ideas for the gallery improvement are break down to some simple
tasks like that you guys could use Google code-in to do it.

It seems this was the only source of errors.  There is a pull request here:

https://github.com/matplotlib/matplotlib/pull/713

There are plenty of warnings that should probably also be dealt with, 
but this at least allows compilation to complete for now.

You could still have a one-page gallery with plots separated into
subheadings (and a table of contents at the top which allows you to jump to
subheadings). This alone would greatly improve navigation in the gallery.
The list of headings is great, by the way.

An advantage of the current all in one page gallery is that it is
easier to find a recipe when I just look for individual plot elements,
when I have not much idea what it might be called and just some idea
what it should look like.

That's different from looking for plots with a specific usage or content.

I think you are correct - and I think the fact that the line width of the
error bar is larger (compared to the size of the rectangle) gives the
impression the top rectangle is actually darker.

I see - it's just a matter of playing around with the error bar properties
to make it look pretty.

Thanks,

Federico

I agree, but the current matplotlib gallery is rather clueless about what the examples are related to until you click an image. I'm personally using the gallery by looking at an example that match what I've in mind most closely and then look at the code. But you're right, some structure(s) would definitely help.

Here is an example of a well structured gallery: http://www.gigawiz.com/aagraphs.html.

The first-level structure is organized at:

Specialized Scientific Graphing
Scatter Graphs
Contour Charts (2-D, 3-D, and Ternary)
Heatmaps
Voronoi Diagram
Waterfall Charts
Bubble Charts
Spider Charts
Polar Charts
Column and Bar Charts
Area Charts
Line Charts
Combination Charts (Column-Line, Bar-Line, Area-Line)
Diagrams of Multiple, Independent Value-Axes Column, Bar or Area Graphs
High-Low, (Open)-High-Low-Close, and Range Charts
Pie Charts and X-Y Scatter Pie
Vector Charts
Statistical Charts


Maybe we can find/agree on similar structure(s)/sub-structure(s) and adapt it to the current gallery ?

Here is an example using wireframe().  This method of animation is not
recommended anymore, but it does still work.  Once you get your
plot_surface version working, there are some various tricks to speed it up
and make it more efficient.  Probably the most important thing to remember
is that your norm object will need to be set before starting so that the
colors are consistent throughout the animation.

Sorry, I am not seeing what you are saying.  Just to be clear, when you say
"bar", are you referring to the gray rectangles that denote the mean or the
errorbars that denote the standard deviations?

What might be confusing is that in the first graph, the "cap" of the
errorbars (the horizontal line on the ends of each errorbar) is almost the
same width as the gray bars themselves.  This sort of makes it look like
there are two gray bars stacked on top of each other.  Is this what you are
referring to?

Ben Root

Hi,
I have an array defined by 3 variables p(x,z,t). I would like to produce 
a surface plot with colors defined by p and animate it. That is plot the 
value of p at all x and z, over time (t).  My code to get p is below but 
I really have no idea how to plot this. Anyone know the best way to go 
about this?
thanks,
D

Hi Ben,

In the pre-resizing pictures, each bar is drawn as two rectangles, the
first until the lower margin of the standard deviation, the second until
the mean.

It looks like it draws one rectangle from:

0:(MEAN-STD)

and another from:

MEAN-STD to MEAN+STD

After resizing, it is just a single rectangle with the standard deviation
drawn as normal.

I presume the 2nd version is meant to be correct, but absolutely no
graphics properties are altered (besides manually re-sizing the window).

THANKS, Nicolas.

This is a nice initiative, but I believe that in the context of a 
presentation of some software, this is not the way I would have chosen. 
Why people look-up /such/ galleries? Why I do it myself? What are the 
needs of my students (about 20 - 30 guys who work with matplotlib week 
after wek)?

Often because I want to find a concrete program, which answers a 
concrete question : how to implement timed animations. How to make 
multiple plots. How to insert a figure in a GUI with widgets, how to 
distort an image matrix, etc. etc. So a gallery should contains infos 
about what the hell the example XYZ is about, what does it show, where 
is the *concrete* documentation page with the description of the tools 
used, etc.

The order of examples should be rational, and as ALWAYS some cross-links 
would be useful.
Program-sources without comments are not so useful...

But I believe that this is just a start, and I am aware that to 
criticize is easier than to do something. (Je suis un grognon né, 
Nicolas, désolé...). So please, continue, my heart is with you!

Nicolas,

Thank you for sharing.  Currently, our examples are organized by
subdirectories.  In fact, the Gallary has the exact same examples as the
Examples page (except for animations).  Perhaps the most simple solution
for the gallary page is to just break it up into the subsections by
directory?

Cheers!
