Oh, wait a minute, you are doing a Frameworks install on a Mac. I think
there are others here that might be able to comment on Mac installs.

Sorry, it isn't a developer wiki (numpy and scipy have that...).  But here
are the requirements to make sure that they are installed.

Hi Ben,

Thanks for the tips. How do I check the TrueType fonts? Googling matplotlib
developer wiki doesn't turn up anything. There isn't anything in the
~/.matplotlib directory. I just went ahead and recompiled numpy and
matplotlib, and got the same error.

Re: [Matplotlib-users] Symbol not found

[Benjamin Root]

Ranjit,

There are a couple of possibilities.  The first is that the TrueType fonts
packages weren't detected during the build, so matplotlib compiled without
it, leading to your issue.  I have also seen an issue where your
~/.matplotlib/ needs to be cleaned out of font-related files.  Another
possibility has to do with building both numpy and matplotlib.  I have found
that if I update the numpy source code and rebuild it, then I have to
rebuild matplotlib. Now that you managed to get a complete build.  I would
go back and completely eliminate the build directories of matplotlib (and
numpy, if you have it), and rebuild.  Build numpy first if you have that
from source, and then build matplotlib.

So, first double-check your TrueType Font packages and see if you comply
with the dependencies listed on the developer wiki.  If so, then check your
.matplotlib directory for any fontCache files and remove it.  Lastly, do a
complete clean and rebuild of matplotlib (the cleaning part is very
important).

I hope that helps,
Ben Root

Success! (well, the import worked)

Christoph, thanks so much for the link, it is awesome! It can't be said enough 
that this is an awesome project and I'm so glad and thankful that it exists.

Re: [Matplotlib-users] basemap broken with matplotlib 0.99.3?

[Christoph Gohlke]

IIRC basemap contains Cython code, which would need to be "recythonized" 
with the latest Cython version in order to work with numpy 1.4.1. If you 
don't mind trying developer releases, use basemap 0.99.5 from 
, which should work 
with numpy 1.4.1.

Bill,Paul:  I'm pretty sure this is due to a binary incompatibilty 
between cython extensions compiled with numpy < 1.4 and numpy >= 1.4.  
The installer was probably created with numpy 1.2.1, and you  have numpy 
1.4.1.  Unfortunately, I don't have the ability to make windows 
installers, so you'll either have to compile basemap yourself on 
windows, or downgrade your numpy.

Re: [Matplotlib-users] basemap broken with matplotlib 0.99.3?

[PHobson]

Bill,

Unfortunately, I don't have a solution for you. I just wanted to chime in and 
say that I'm getting the same error. I'm on XP, py2.6, mpl0.99.3, np1.4.1, 
sp0.8.0b1. Basemap came from the latest Windows binary on Sourceforge.

I'll be ok for the time being.  I've been using matplotlib, scipy, and numpy 
(and variants) for the past 5 years or so on OS X.  Every time I go to 
upgrade, the recommended procedure changes.  The previous version still runs 
however, so I'll survive.

It would be useful though to make a note for whoever packages official 
releases of matplotlib for OS X to make sure they are targeting the 
python.org install of python.  numpy and scipy also do this.  It makes it a 
lot easier to push python as a Matlab/IDL replacement if potential users can 
just download four dmgs (python, numpy, scipy, and matplotlib) and it all 
just works out of the box.

Thanks for the help!

Tim

Well, it's not the worst thing in the world to use Apple's python, but I 
still don't think that it's the best either:
   - The Apple python has never been updated
   - Anything built for it will only work on 10.6
   - you can't use py2app and get a fully self-contained binary
   - I can't remember the others.

Anyway, it's been common practice to build binaries for the python.org 
python -- it's the way to reach the widest audience. MPL used to do 
this. I suspect the latest binary is a mistake, but if not, it should be 
Clearly labeled as for the ApplePython2.6-osx-10.6, and ideally, a 
python.org compatible binary provided as well. I'm sorry I can't find 
the time to do that myself right now.

Re: [Matplotlib-users] Reverse y-axis?

[Joe Kington]

There's no single function to do it, but just reversing the current ylimits
manually is a one-liner.  ("plt" is "matplotlib.pyplot", here)

plt.ylim(plt.ylim()[::-1])

Hope that helps,
-Joe

If using the OO interface:

axes.invert_yaxis()

or

axes.set_ylim(2000, 0) # note the larger value first

or with the pylab interface:

ylim(2000, 0)

FWIW, I have had exactly this same problem, though I have not attempted
the very helpful instructions others have supplied in response to this
thread.

I am in the undesirable situation of using different Python
distributions depending on what features I require: either my "main"
copy, for most operations (some other applications I have installed will
only use this), EPD (32-bit) when I want all the bells and whistles of
EPD, and in some circumstances I opt for a customized version of Sage
Math which includes specialized packages that install easily.

I think that underscores the problem.  The matplotlib OS X dmg installer 
installs matplotlib in the site-packages directory for the system default 
install of Python (2.6.1).  Everywhere I read insists that on OS X you 
should install python.org's python, which puts it's site-packages in the 
location you say.  The numpy installer puts stuff in the right place.  But 
matplotlib is not there.

To clarify, I've taken screen shots of the 0.99.3 and 0.99.1.1 dmg 
installers.  If you look in the bottom pane of the window, you will see the 
install location which you cannot change.  The 0.99.1.1 installer places 
files in the appropriate location for python.org 2.6.5.  The 0.99.3 
installer places files in the appropriate location for the OS X bundled 
version of python (2.6.1) that we have been warned not to use.

[Matplotlib-users] Reverse y-axis?

[Preben Randhol]

Hi

I need to plot some data vs depth. In stead of giving depths as
0,-1000,-2000, I want to give the depths as 0,1000,2000 but when plotting
the data goes downwards (as if they had been negative). Can I get the
y-axis to reverse so it goes downwards and not upwards?

I have followed these instructions to (almost ) the letter.
Only difference is that python was already installed at 
/Library/Frameworks/Python.framework/Versions/2.6/bin/python
I also re-installed numpy.

Still no good with always the same problem - the absence of numpy.core.ma

Any suggestions?

[Matplotlib-users] scatter plot with discrete colorbar

[German Ocampo]

Hi

 I'm using the following code for insert a scatter plot in a figure in Qt.

vmin=min(r_time[:])
vmax=max(r_time[:])
valores=np.arange(vmin,vmax+1)
a1=self.ui.axes4.scatter(r_east,r_nort,vmin=vmin,vmax=vmax,c=r_time,edgecolors="none")
b1=self.ui.fig2.colorbar(a1,values=valores,format="%.3f",spacing="uniform")

The plot is ok and and the colors in the colorbar are ok, but for
some reason the  ticks are missing. I tried

b1=self.ui.fig2.colorbar(a1,values=valores,ticks=valores,format="%.3f",spacing="uniform")

but still the ticks doesn't appear.

How can I get the ticks in the colorbar?

Thanks

German
