Hi all,
I have managed to create a 3d plot with uneven aspect ratio via
auto_scale_xyz but I haven't yet figured out how to fix the grid. If you
could give me a pointer I would appreciate it.

Yes, that works. Many thanks.

This is an autoscaling issue, I think. Your best bet is to explicitly set
the x limits yourself.
Cheers,
Ben Root

I am trying to get alternating tick labels to move completely above and
completely below the x axis. If I call:
 set_ha('top')
... then the number appears fully below the x axis. However, when I call:
 set_ha('bottom')
... then the number appears roughly vertically centered on the axis.
I am aware that vertical alignment only matches text to its bounding box.
Is there a way to move this bounding box? I have tried calling set_position
on the text but this seems to have no effect. I would be grateful for any
suggestions as to how I can move the tick labels appropriately.

If I do:
 bar(range(3), [1,0,2])
... then I get 2 bars of a suitable width for a 3 bar chart, with a gap in
between where the middle bar would be if not equal to 0. Yet if I do:
 bar(range(3), [1,2,0])
... then I get two bars of equal width. Is there a way to preserve the
space for the missing bar?

Michael: I just meant for you to paste the full output, not just the 
first three lines.
Since you apparently have all the libs installed, I don't understand 
what's going on. Please try deleting the netcdf4-python build 
directory, and then run 'python setup.py build' again, capturing the 
output in a file. Send me that file off-list and I'll see if I can 
suggest something.

Michael: You're missing the hdf5 library. You should be able to
 install that (along with the netcdf version 4 library) using the
 Ubuntu package manager. I don't know what the relevant package names
 are.
See the docs at netcdf4-python.googlecode.com for installation instructions (including how to install the dependencies). 
You can also file a help request there and I'll see it (since this
 is not really a basemap issue).

Just installed h5utils from package manager. Getting same errors. In package manager I'm searching on hdf5. If there's a package there I'm missing, then it certainly is not obvious.

Hi All,
 I am currently trying to plot 4 points (but they will be more, in
an animated sequence later), and I am trying to use an image as a
point marker. I am using the axes transData transform to get the point
coordinates from the data world to the display world.
Everything seems to be working OK (i.e., the images are placed
correctly close to the plot points); however, as soon as I try to
force the axes into an "equal" aspect ratio with this command:
ax.set_aspect('equal')
Then all the calculations are messed up and the images end up very far
from the plot points. I have tried also the approach mentioned in this
StackOverflow post:
http://stackoverflow.com/questions/2318288/how-to-use-custom-marker-with-plot
But I get the same wrong answer when I set the "equal" aspect ratio
for the axes.
I am attaching a small sample application which demonstrates the
problem, a small "smiley.png" image needed to run the script and two
plots generated by my script, one with the "equal" aspect ratio and
the other without.
I appreciate any suggestion, as I feel I am missing something important...
Thank you in advance.
Andrea.

Sean,
I *think* the best way to do this is use multiple GridSpec objects
within a single figure. Does this example help?

I wonder if hspace and wspace in gridspec should take arrays like 
width_ratios and height_ratios. Try axes_grid1 instead.
http://matplotlib.org/mpl_toolkits/axes_grid/users/overview.html#axes-grid1
(though the documentation is not the best)
I think this example does what you want:
M
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np
clf()
ax = plt.subplot(111)
im = ax.imshow(np.arange(100).reshape((10,10)))
divider = make_axes_locatable(ax)
ax1 = divider.append_axes("right", size="100%", pad=0.0)
im1 = ax1.imshow(np.arange(100).reshape((10,10)).transpose())
cax = divider.append_axes("right", size="5%", pad=0.05)
plt.colorbar(im1, cax=cax)
plt.draw()

oh, o.k., I will read up on that...for now, with python, I simply plotting
one instance at a time and saving every image; then, with ffmpeg, gluing the
gluing the images together from the command line.
thanks

Hello all,
I want to adjust the wspace used in a gridspec plot on a cell by cell basis. Anyone have suggestions for how to do that? I haven't been able to find an api to do that directly.

This should get you started. Unfortunately, the documentation is very
sparse, but the examples should be illuminating. Note that you will need
to have either ffmpeg or mencoder installed if you wish to save any of
these to movie files.

Animation/movie advice.
So, earlier, I got some help in finding out about pcolorfast that allowed me
to plot some data as a nice contour.
Now, I would like to get fancier and actually take a look as such contour as
it varies with time...
how to go about it? 
some kind of animation? or movie?
If I want to do one cycle wt=0..2pi rad, or equivalently, wt=1..360 deg, I
could go ahead and create all 360 contours ahead of time, save them, and
them somehow display them in a sequence.
I just have never done animation or gluing pictures into a movie.
Any advise would be greatly appreciated.
Thanks,
Germán

Michael: The NetCDFFile function was deprecated a few releases back, and recently removed. If you have netcdf4-python installed you can do
from netCDF4 import Dataset as NetCDFFile
and the script should work as before.
Regarding the second error, you must open the file for write access
 (mode='w') if you want to add attributes to the data variables.

Making some progress. Following here:
http://code.google.com/p/netcdf4-python/wiki/UbuntuInstall
I've installed HDF5 after installing build-essential package. With just gcc installed I got an error.
The ./configure in netcdf4 directory failed, but completed with --disable-netcdf-4. I went ahead anyway hoping I don't need netCDF-4 formats or the additional netCDF-4 functions. Besides that issue, what's also not clear is where is setup.py file for the last step. It is not in the netcdf directory after the make install finished. I assume netcdf-python package will not conflict with the python-netcdf and netcdf versions installed through package manager.

Got sidetracked with an OS issue. Back on the case. Where is the setup.py file I'm to install? I've installed both HDF5 and netcdf-4, correctly I hope.

Sorry -- I seem to have missed that in the transition from Sourceforge
