matplotlib-users Mailing List for matplotlib (Page 7)

Here is a (limited) SVG path parser I made some time ago:
https://github.com/rougier/LinuxMag-HS-2014/blob/master/matplotlib/firefox.py
The svg_parse function might just do what you're trying to achieve.

Hi Marin,
+1 for the idea of specific papers. For example, all PLOS require the
same figure format and I have my own config file. I'd be more than
happy to dig into it and try my best to contribute.

Hi,
I started working on styles based on which support the figure is 
designed for (as of now, I've got 'paper', 'notebook', 'talk', 'poster').
For those, in a style point of view, I think only the text size should 
be modified (got it done, just need to get the proper sizes for each 
style), which is unlike the 'seaborn' way of doing it. Thing is, by 
doing so, we don't mess with any style we could apply using Cascading 
styles.
Also, I was thinking that I should set the export settings for each of 
those styles, but also get an export style folder (with a few good 
parameters). This would mean no more need to adjust dpi, file format, 
figure size...
Finally, I could add a folder for specific papers, in which the figure 
parameters would be tweaked so that we can directly be in a specific 
paper format. I guess it would take into account both text size and 
export parameters for each paper.
Let me know what you think about it.

Hi,
I have some SVGs with closed Bezier curve paths that I'd like to convert to
matplotlib paths.
For example, here is some code:
https://gist.github.com/moorepants/4cac02e798446bb46de7
The above script runs but the resulting path in matplotlib is less smooth
that when opened in inkscape, for example. I've attached screenshots.
I'm not sure why there is a difference.
Any suggestions to get my matplotlib curves looking as smooth as they do in
SVG format?

Another advantage of a separate repo is that it would make it easier for
multiple projects to participate. The process could be set up so that
projects like seaborn, ggplot, and prettyplotlib could keep their
stylesheets in the same project, and have the stylesheets project have a
release whenever any project needs to update stylesheets. Using a "master
is always stable" development model would make that easier.

A similar pattern with `matplotlib.style` would use chained stylesheets.
The idea would be to make stylesheets either aesthetics focused or layout
focused. By aesthetics, I mean things like colors and marker shape, and by
layout, I mean things like default figure size, figure padding, font size,
etc. Then you can easily have a style that defines the general aesthetics
and easily modify it for papers, talks, etc.
Here's an example from `mpltools`, but the same syntax applies to the
`style` module in `matplotlib`:
http://tonysyu.github.io/mpltools/auto_examples/style/plot_multiple_styles.html
(PoF = Physics of Fluids journal; IIRC I think I have some personal
stylesheets that take the normal two-column figure layout and convert it to
a full-page layout.)

Maybe a dumb question, but I'm quite new to this...
Can this be integrated in mpl afterwards? Or does it needs to be a 
standalone package that you install on its own?
If it can be integrated, how?
Thanks

I was thinking of the stand alone repository to just store the style files
as the style module handles the loading pretty well.
The main motivation for this would be to decouple the release cycle of the
styles (which can be very fast) from the library (which needs to be slower).

I see seaborn has "paper, notebook, talk, and poster" options.
http://stanford.edu/~mwaskom/software/seaborn-dev/aesthetics.html
Apperantly he scales each parameter to get modified views. This would be a
good addition for any of the styles available in matplotlib.

You mean put a stylesheet name in a list and then load it?
If that is the case, it is indeed possible. You can look at 
|matplotlib.style.use| 
<http://matplotlib.org/api/style_api.html?highlight=style#module-matplotlib.style> 
to do that.
If you want to change parameters (like text font, size, color...) from a 
list, it seems to me it is possible, but I guess you would have to use 
rc parameters in your script.

Indeed it would be a very good idea.
I've seen that already in the seaborn lib I guess.

When you say *style library*, I’m not sure exactly what you mean...
It would be just more stylesheets, or a full python lib to manage the 
styles?
The latter would be the most interesting for me (as that is what I had 
in mind when starting this thread), but after digging in mpl, it seemed 
that the actual style management system is quite good... Unless there is 
some caveat I am not aware of.
In that case, could you point out what you have in mind (if anything)?

It would be good to have styles for "paper" and "presentation" modes. The
former would have smaller ticks, labels, linewidths, other axis elements
that goes into a journal publication, while the latter with much magnified
elements to be clearly visible on a screen from the back of a room.

Sure, I'll be careful about that.
I'm going to go try and design some new interesting ones.
Maybe adding some styles specific to some plot types could be useful.
Also some styles specific for some applications (geoscience, biology)?
If you have any other ideas, please let me know.

Yes, we are interested it more built-in themes.
It may be worth making a 'matplotlib-styles' project which is _just_ a
style library.

I certainly think it would be beneficial to have more available styles. It
certainly would help exercise this particular aspect of matplotlib.
One caveat from past submissions. Please do not include
copyrighted/trademarked styles. So, no "matlab style" or "mathmatica
style", etc...

Hi Christian,
I saw them indeed.
After looking into it in more details, it seems that the default styles 
are defined in a config-like style.
It is possible to create your own styles and put it in your config path 
so they are accessible (Style on matplotlib.org 
<http://matplotlib.org/users/style_sheets.html?highlight=style>).
Also, Would the community be interested in more integrated themes?
Thanks for your help

Hello everyone,
I was wondering if there would be some kind of plot style profile interface.
What I mean, is that you could have mutliple files with different styles 
for plots, that would be used to change easily the style of plots.
I know about the |matplotlibrc| but I am thinking of something a little 
bit more flexible, which could swicth between multiple "style sheets" 
easily.
As an example, for now I use the Seaborn 
<http://stanford.edu/%7Emwaskom/software/seaborn/index.html> |set_style| 
<http://stanford.edu/%7Emwaskom/software/seaborn/tutorial/aesthetics.html#styling-figures-with-axes-style-and-set-style> 
capabilities to get better looking graphs.
I previously used Prettyplotlib 
<https://github.com/olgabot/prettyplotlib> to make better plots.
But with those two libraries, it does not seem to me that you can 
control your graph settings with, for example, a config file.
Thank you
​

instead of having people enter all this info by hand, you should just
write a python script that extracts most of the technical details from
the current install, prints it out for cut-and paste into the form or
directly sends it to your server. ;-)

Hi everyone,
If you use scientific Python packages for your research/work, I would
appreciate if you could take a few minutes to fill out the following
survey:
 http://goo.gl/PXzFAk
The aim of this survey is to find out what versions of Python and
various scientific Python packages people are using, and how people
typically install packages, in order to determine how developers can
better meet the needs of the Scientific Python community (for example,
a common question is which version of Numpy need to be supported by
packages).
This is a follow-up to a similar survey which I did back in 2012 and
which provided very interesting results that you can read about here:
 http://astrofrog.github.io/blog/2013/01/13/what-python-installations-are-scientists-using
Please feel free to forward this survey to people in your own
scientific Python communities!
I will publish the results online in a few weeks.
Thanks!
Tom

Hi, all
 
The following code repeats the problem. Array ele1 is same as ele2 except that it is transpose of ele0, but the refined triangles using ele1 is incorrect.
The problem is also reported at https://github.com/matplotlib/matplotlib/issues/4180
matplotlib version: 1.4.0, the UniformTriRefiner code in version 1.4.3 is the same as 1.4.0。

Not with contourf(), no. But, you can always add many Text objects after
plotting the contourf() (just loop over the dimensions of your array at
some stride and add Text objects at the appropriate coordinates). In fact,
there might even be a feature coming up soon that would make this sort of
task easier: https://github.com/matplotlib/matplotlib/pull/4063
Cheers!
