matplotlib-devel Mailing List for matplotlib (Page 3)

Hi All,

I've attached a patch which optimizes a particular case of the
RegularPolyCollection.get_transformed_patches method. This is
particularly useful when using a picker on a scatter plot with ~40,000
points (as I happen to be doing) and cuts the time spent in this
function from ~4s to ~1s, which accounts for about 50% of the lag in
my particular use case.

Similar improvements might be possible in the N > 1 case, but I don't
have a) a data set or b) the time to work them out with, so hopefully
someone is happy to check in this patch as it stands, as I think the
N==1 is probably the common case.

If there are any problems with the patch let me know and I'll try to
fix it up. It's against latest svn (3262)

Cheers,

Tim

Hi all,

Thanks for all of the feedback for my early release of WebLab, a web front 
end for Python and Matplotlib. Based on your comments I am releasing a new 
version with the folowing enhancements:

- Works on Windows XP, Linux and Mac OS X
- Released under MIT license
- Completely rehauled user interface (see some nice screenshots in the 
website)
- easy access to matplotlib functionalities
- A simple dialog toolkit for adding interactivity to the program
- syntax highligting text editor
- fully functioning online file manager

Some of the planned features for near future are:
- Data import and viewing utility for CSV or Tab limited file. The data will 
be directly loadable into numpy matrix for easy access
- More built in tutorial, possibly an integration with Crunchy 
(http://code.google.com/p/crunchy/)
- Host the project in Google code website.

You can find all of the goodies here:

Enjoy,


Yusdi

Hi,

I have a modified version of the TkAgg backend, with a few custom
features, and would like to be able to get pylab/matplotlib to use it,
but without having to put the backend code into the matplotlib code
tree.

Is there a way to make matplotlib find and use a "backend_xxxx.py"
which does not reside in matplotlib/backends/   , and without filling
in entries in matplotlib/__init__.py and
matplotlib/backends/__init__.py  ?

Thank you very much.
Regards,
 Urvashi
