matplotlib-users Mailing List for matplotlib

Hello,

Thanks for the pointer Bryan. I also seen Gael's tutorial (
http://gael-varoquaux.info/computers/traits_tutorial/index.html)

To me, it seems much easier to use Traits, instead of learning WX or QT.
They are still confusing to me, and seemingly Traits is there to help me
implement what I have had in my mind for a while.

Ok, that sounds reasonable.

I mentioned C++/C because I am interested in using it in my computer
algebra system (http://www.aei.mpg.de/~peekas/cadabra), and its user
interface is currently written in C++ using gtkmm. C++ is fairly
widely spread in the scientific community too, in some fields much
more than Python.

Since the user base for a TeX typesetting library isn't particularly
large (compared to other libraries), it's probably good to at least
keep in mind that people might want to call this from a non-Python
language (even though I will probably be tempted to convert my code to
Python). In any case, having a Cairo backend will help.

Cheers,
Kasper

You can integrate matplotlib plots into a Traits app. I wrote this
recipe:

http://www.scipy.org/Cookbook/EmbeddingInTraitsGUI

Both Chaco and Matplotlib are excellent. If you want multiple
interactive elements in your plot (drag-able labels, cursors etc.),
Chaco is probably the best bet. However, for quick data-exploration
apps, I find matplotlib quicker to set up (it's defaults "just work",
whereas Chaco takes a bit more preparation).

Either way, Traits is indispensable.

Add the rotation keyword argument:

xticks(arange(5), ('Tom', 'Dick', 'Harry', 'Sally', 'Sue'), rotation=45)
