imshow remove

Hello List,

Normally, something added to axes in
a plot can later be removed by
saying element.remove(). All but
images, for example plotted with imshow,
since they lack a _remove_method.

Is that a bug or a feature?

Greetings

Martin Teichmann

Re: proposed change to colors.py


Hello Ryan-

Unfortunately, I'm on a Windows system, and it appears that I must use SVN's
GUI interface, which does not provide a mechanism for saving the diff to a
file.

[PATCH] experimental numscons support in matplotlib

Hi,

    I don't know if that's of any interest for matplotlib developers,
but I added scripts to build matplotlib with numscons:

http://github.com/cournape/matplotlib/tree/scons_build

Not every configuration is supported yet, but I can successfully build
matplotlib on Linux with gtk or wx backends. It only adds 3 files + one
configuration example, and does not touch any other file.

The advantage of numscons over distutils is automatic dependency
handling (no need to rm -rf build to get accurate build), easy compiler
flags customization, parallel build, etc... There are some instructions
in setupscons.py.

It is still experimental (I have not implemented check for QT, as well
as windows, macosx and qt backends), but it seems to work well. I will
add mac os x and windows backends soon (I started this to debug issues
on 64 bits version of matplotlib),

cheers,

David

Hi Jouni,

I just installed gs on one of the buildbots -- so at least the .pdf
generation should get tested on one machine. (The one running the py24
and py25 tests.)

As far as the decorator turning one test in into multiple tests out --
it may be possible. Nose does this automatically for tests like:

def check_sum(func):
    a = 10; b = 20
    assert a+b == func(a,b)

Dear David,

It certainly is of interest to me. When I get a little time (maybe this
weekend), I'd like to try it. Specifically, I'd like to setup a buildbot
that would automatically build and run the test suite with it. Along
those lines, is there any reason why it shouldn't work with Ubuntu Hardy
amd64 (8.04) and Python 2.5? Or should I try another distro? (I'll be
setting up a chroot.)

It should work on any distro. I have not tested this really hard yet,
though - but it already works better for me than the current setupext.py
(I may miss something, but the detection fails horribly on my machine,
especially for libs not installed in /usr).

There are some configurations which are not supported yet (wxpython <
2.8, tkagg, and  win32 + mac os x backends), but it should be relatively
easy to add support for it, except maybe for mac os x backend because of
objective c because numscons does not handle objective C yet (my focus
is windows ATM, but if supporting every configuration is a condition for
the patch to be included, I am willing to work on it).

The patch could be made smaller and more robust if I were allowed to do
some basic refactoring to share configuration data between setup.py and

David,

I'm interested also--especially if it would eventually help solve some 
of the build problems that crop up.  (I already use scons in another 
context, and that helps make me receptive to numscons.)
