Craig:  It's hard to imagine how you can hose your system by installing 
a fink package from source.  Don't be afraid - just type "fink 
selfupdate" then "fink install matplotlib-py23" and let me know off-list 
if you have any problems (I'm the maintainer of the fink package).

Hello NG,

    I am sorry for the possible stupid question. Does it make any sense to
ask if it's possible to define in matplotlib a Matlab-like command:

box on

or:

box off

In order to draw/undraw the axes bounding box?

Thanks in advance.

Andrea.

This helps with the previous linking error, but now it's not looking  
for libpng the right place.  (it's in /sw/lib)  *argh*

I'd *like* to use the fink version.  I've been trying to stick mainly  
to the 10.4-transitional binary distro.  I'm a fink novice, so going  
to src scares me as I've hosed my setup before.  I guess now that I'm  
a Mac guy (tm) -- I should probably figure it out eventually.  I have

Trees: local/main stable/main stable/crypto unstable/main unstable/ 
crypto
Distribution: 10.4-transitional
-------------------
in /sw/etc/fink.conf.
Is this right?

At any rate, my problem is that when I did a: "sudo fink -b install  
matplotlib-py23" I get this:

I guess this is now off-topic since we've cascaded into fink

David,

Two more things:

1) Have you considered using contourf instead of imshow, or would it be 
inappropriate?

2) Please send me the code for the X array that you used in your example.

Thanks.

Eric

Craig:  If you export CXX=gcc, I think that error will go away.  This is 
what the fink matplotlib package does.  BTW - why don't you just "fink 
install matplotlib-py23" if you're using fink python?

Hi all.

I was wondering if anyone might have any idea why I might be getting  
these build errors.

------------------------------------------

Seems like the problem is that the setup process wants to link  
against /usr/lib/gcc/darwin/3.3/libstdc++.

I'm building with
"python2.3 setup.py build"

where python2.3 is from fink.

However, somehow, it seems like the build process wants to use  
apple's gcc "/usr/bin/g++-3.3", which in turn uses apple's ld "/usr/ 
bin/ld".

Does anyone recognize the "malformed object" error?

Don't know why it's looking for libs in my home directory.

Thanks much,
Craig

David,

It is possible that I made this discretization problem worse when I 
modified some of the color handling code. In any case, I would like to 
come up with one or more good, clean solutions, but I may need a few 
days.  The problem is with the normalization (the norm kwarg), not the 
colormap, which is little more than a list of colors. The trick may be 
making sure any change in the norm code doesn't mess up the way contour 
and colorbar work.

One workaround is to calculate Xindex from X, where Xindex is an integer 
array the same size as X but containing the desired index into the 
colormap for each value of X, and then call

imshow(Xindex, cmap = bone10, norm = colors.no_norm)

I think this should work, but I haven't tried it yet.

Hi,

I posted a problem on the list earlier that didn't seem to make it to the
list. Anyway, It gave me time to solve my problem and the result is this
function that takes as input a .cpt file (a palette file format) and return=
s
a colormap dictionnary.

It can return a continuous or discrete colormap (provided the input palette
is itself discrete) and symetric/asymetric colormap.

Have fun !

David

I needed to validate the verbose settings first, so reports could be generated 
during the rest of the validation process. I hadn't considered that rc files 
might not include these settings. Thanks for the report, it's fixed in cvs.

Darren

I just fixed this in cvs. Try updating again, but if non-dev checkout is 
lagging, you can change line 320 in setupext.py to read:

o.tk_lib = os.path.join(str(tk.getvar('tk_library')), '../')

It appears that the recent CVS versions *require* verbose.level  and  
verbose.fileo to be set in the rc file, as per the lines (923-930)  
matplotlib/__init__.py:

         if i == 1:
             key = 'verbose.level'
             val, line, cnt = rc_temp.pop(key)
         elif i == 2:
             key = 'verbose.fileo'
             val, line, cnt = rc_temp.pop(key)
         else:
             key, (val, line, cnt) = rc_temp.popitem()

What's wrong with letting the default values slide through?

Hi all,

I cannot use subscripts within legend.
See subscript.py for details.

How can I fix this problem ?
>>> matplotlib.__version__
'0.86.2'

Nils

Paul,

This one has tripped up a lot of people.  It is caused by a version 
mismatch between numpy and mpl; you need a more recent mpl to work with 
up-to-date numpy. CVS should be OK, and I think 0.86.2 is also OK.

I'm using numpy in my matplotlibrc.

Here is the error:

Any ideas?

The only thing I can guess is not everything was cleared out from your
previous numarray installation.  Maybe a conflict?!  Try just deleting
"/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packa=
ges/numarray/"
completely and reinstalling.
