Re: [Matplotlib-users] compile numpy with UCS4
When you recompile Python in a new unicode mode, you then need to recompile all extensions (such as Numpy), since an extension compiled for one mode will not work with the other. Annoying if you have a lot of extensions. However, I don't think that UCS4 mode is required for Tkinter -- it could just be that the Tkinter you have compiled was compiled against a Python of a different unicode mode. (RHEL builds its python packages with --enable-unicode=UCS4, so if you're using the RH package for Tkinter with a self compiled Python, that may be what you're running into.)

Is there are way to get the two to play together nicely? Such as recompiling numpy with USC4 support? KURT -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.

Re: [Matplotlib-users] This user name is already in use
My apologies, I misread your post. I was assuming that you were trying to create a github account in order to file a bug report. But again, this isn't a matplotlib issue, this is a nabble issue.

[Matplotlib-users] How to provide colorbars for scatterplots created this way?
I create PNG files of scatterplots with code that, in essence, goes as in
the sketch below:
cmap = (matplotlib.color.LinearSegmentedColormap.
from_list('blueWhiteRed', ['blue', 'white', 'red']))
fig = matplotlib.figure.Figure(figsize=(4, 4), dpi=72)
ax = fig.gca()
for marker in 'o s ^ *'.split():
X, Y, COLOR = zip(*((record.x, record.y, record.level)
for record in data if record.marker == marker))
ax.scatter(X, Y, marker=marker,
c=COLOR, vmin=0, vmax=1, cmap=cmap,
**otherkwargs)
# various settings of ticks, labels, etc. omitted
canvas = matplotlib.backends.backend_agg.FigureCanvasAgg(fig)
fig.set_canvas(canvas)
# IMPORTANT: the generated figure is *not* displayed on the screen, but
# rather it is output to disk as a PNG file:
canvas.print_png('/path/to/output/fig.png')
My question is this:
What do I need to add to the code above to get a vertical colorbar
(representing the colormap incmap) along the plot's right edge?
I word the question in this way because I am not sufficiently facile with
Matplotlib to deviate too far from the working code above.
In particular, my code *has* to be able to produce PNG files
*non-interactively*, so the last line in the code sketch above is really
essential.
Thanks in advance!

Can you provide some more information and a self-contained example? What is
your record object? Is it a pandas dataframe? Are the limits of
record.level consistent with vmax and vmin kwargs fed in the call to
ax.scatter?
Typically you can just do:
import matplotlib.pyplot as plt
# blah blah
fig, ax = plt.subplots()
s = ax.scatter()...
cb = plt.colorbar(s)
cb.set_label('Cbar Label Here')
Also, I don't think you need to mess with the backend stuff. Just do
fig.savefig('figname.png'). If you need separate markers for each set, make
a single call to scatter for each data group, and use numpy to figure out
what the appropriate vmax a vmin limits are for the colorbar.
