[Matplotlib-users] Installing matplotlib with Mac OS 10.6

[Lisa M W. <Lis...@Co...>]

Hello.

I am finding it very difficult to install matplotlib with snow  
leopard.  I have the Apple XCODE installed along with numpy (which I  
have tested and works) and am running the python 2.6 version that  
comes with the Mac.

I have run into the following problems:
1) The diskimage installation: When I open the installer, I am told  
that I can not install matplotlib on my disk because I do not have a  
system version of python 2.6.  I do not understand this error since I  
am running the default version (which is 2.6.1).

2) As another person on the list pointed out, easy_install matplotlib  
tries to install an older version that does not work with the newer  
version of numpy.

3) I downloaded the matplotlib-0.99.1.1-py2.6 egg.  I was able to  
install matplotlib, seemingly.  When I import pylab into python, I do  
not get any errors.  However, I do get an error when I try to plot.   
With the default backend TkAgg (version 8.5), I get the following  
error when I try to plot:
_tkinter.TclError: integer value too large to represent

When I try to change the backend to MacOSX, a window opens labeled  
Figure 1, but nothing plots.  With the verbose level on helpful, I  
find only that "backend MacOSX version unknown".

Has anyone seen any of these problems before and have an idea as to  
how to fix this?  If not, is there another method that I should try  
(I'm hesitant to try to build/install from the source).

Thank you for any help!

[Matplotlib-users] Saving a plot to EPS

[Michael C. <mc...@ca...>]

Hi all,
I made a typical plot, and tried to save it to EPS.  The resulting file 
is un-openable in gimp, the gnome thumbnail viewer, evince, and anything 
else I have tried.
Is there any problem saving a plot to EPS at the moment?

Cheers
Mike

[Michael C. <mc...@ca...>]

Hi,
To add more information.  I am trying this on two separate installs of 
matplotlib 0.99, both using TkAgg as the backend.  One produces an 
unreadable file, the other does produce a readable EPS.  However, even 
in this case, zooming in on the image shows that what is being saved is 
bitmapped, not a vector graphic.

Cheers
Mike

Could you please post some sample code and the EPS it generates, as
well as platform information and any specific rc settings you may
have?

Hi,

Sorry for taking a few days to reply.
Basic system information

$ uname -a
Linux shc-b 2.6.18-128.1.10.el5 #1 SMP Wed Apr 29 13:53:08 EDT 2009 
x86_64 x86_64 x86_64 GNU/Linux
$ head -n1 /etc/issue
Red Hat Enterprise Linux Server release 5.3 (Tikanga)
$

matplotlibrc attached.

plot_test.py attached also.

$ python
Python 2.6.2 (r262:71600, Sep 16 2009, 13:37:23)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import matplotlib
 >>> print matplotlib.__version__
0.99.0
 >>>

finally, failed output eps also attached.

The plot generates a set of horizontal and vertical lines to make a 
grid, and then applies the Mollweide projection to give latitude and 
longitude lines.
For some reason, not running the projection (i.e. lines 43-51 in the 
python script) gives a file that outputs as a nice eps.  If you do keep 
the Mollweide projection in, you still generate a lovely plot, but the 
savefig to .eps fails.

Thanks,
Michael

I can confirm this bug on matplotlib-0.99.0, and 0.99.1.2, but not on 
SVN head.  I think this is related to a recently fixed bug involving the 
renderer outputting single-point lines (which obviously doesn't make 
sense, and Postscript has problems with).

You can either install from SVN (I recommend using the 0.99.x branch 
[1], rather than the trunk), or set the rcParam 'path.simplify' to 
False.  Unfortunately, the latter will result in some very large file sizes.

Re: [Matplotlib-users] Installing matplotlib with Mac OS 10.6

[William C. <wcc...@lb...>]

Hi Lisa,

I had lots of trouble installing on 10.6 as well. What finally worked for me
is to use the (recommended) file make.osx that comes with the matplotlib
download. You have to edit that file to point to the versions of Python (you
want 2.6) and OSX (you want 10.6). I'm attaching a version that has all
these edits already made. (I'm assuming you have an intel Mac, not a ppc).

Look at the top of the file and you will see an example command line that
begins with PREFIX. You'll execute that command line with the example
directory changed to your directory and I highly recommend choosing the
directory /Users/(whatever your user name is)/.local  All the libraries will
be installed there and Python will know how to find them even without
explicitly putting them in any PATH variable. This command line will even
check for required dependencies like freetype2, pnglib, ... And will go them
and install them for you if you don't already have them. The command line
should look like:
sudo PREFIX=/Users/(your username)/.local make -f make.osx fetch deps
mpl_install

Good luck,
Bill

Thanks for the pointers, Bill.

I tried installing from source as you suggested, but I am getting the

Re: [Matplotlib-users] Installing matplotlib with Mac OS 10.6

[William C. <wcc...@lb...>]

Hi Lisa,

Hmm. I also use TKAgg with no problems. Looking at your code, it looks like
you are trying the first example in the tutorial. Just to be sure, could you
post/send a full listing of your simple_plot.py?

Thanks,
Bill

Sure.  This is all that it is:

from pylab import *
plot([1,2,3])
show()

Re: [Matplotlib-users] Installing matplotlib with Mac OS 10.6

[William C. <wcc...@lb...>]

You're right--that's pretty simple. I ran that exact code and it worked
fine.

Don't know what to say except that this is above my competence level to dig
into the guts of tk. Looks like a problem for John Hunter.

Sorry I couldn't help more,
Bill

The diskimage is usually built for the python binary supplied by 
python.org -- that is what the message means by the "system version". I 
tried to submit a patch to change that message a year or two ago, but I 
guess it never got applied -- maybe I'll try again.

A note to developers/distributors:

Robin Dunn figured out a way to install a binary wxPython that will work 
with both the Apple and the python.org binaries. What it does it put it 
in /usr/local, and then put a pth file in both of the pythons so that it 
can be found. A bit of a hack, but it works, and I've never heard anyone 
have a problem with it.

Perhaps we should do the same thing with MPL -- I'm sure he'd be glad to 
share his scripts for building it.

I took a look at the source for the latest bdist_mpkg -- it looks like 
it should now give a message like:

"This package requires MacPython to be installed"

though It's all a bit complicated -- did whoever built the dmg use the 
latest bdist_mpkg?

But maybe should still do:
