Re: [Matplotlib-users] ssh options
Perhaps I misunderstand the question. How is this question specific to matplotlib and not remote login in general? If you need an SSH client for Windows, I use putty, and it works pretty well. If you need X11 remoting or something, I've used Cygwin, and I know others have had success with X-Ming. Does that answer your question?

[Matplotlib-users] Howto? Multiple hist's (subplot) with same axes, without squished bars
Hi,
I'm a matplotlib N00b and I have
from pylab import *
multimap =
...
figure(1)
for index, key in enumerate( multimap.keys() ):
p = subplot(6, 5, index+1)
xlabel('intraclashes kcal')
ylabel('count')
p.axis([0,70,0,0.2])
vals = multimap[key]
#p.set_autoscale_on(False)
p.hist(vals , 20, normed=True, facecolor="red")
show()
===
And depending on if I comment or uncomment the
#p.set_autoscale_on(False)
I get either variable axes ranges
http://people.binf.ku.dk/biehl/penelope/mpl_var_axes.png
or squished histogram bars
http://people.binf.ku.dk/biehl/penelope/mpl_fixed_axes.png
Is there a way to fix this?
Thanks,
Anders

[Matplotlib-users] How to remove the grey border in the plotting?
Hello, I wrote a Python application using GTK+ and Matplotlib. I normally use the application in full screen mode (1680x1050). There is a big gray border. You can reproduce it using the embedding_in_gtk.py from the examples and full screen it. How can I remove this grey border? The numbers on the axes should not be cropped.

[Matplotlib-users] setting up matplotbib
Hi all, I am trying to setup matplotbib on my computer (which is unfortunately running on windows) and for some reason, it doesn't seem to be working. I believe I have downloaded everything I should have downloaded (Python 2.5, numpy, ipython, lpng1226, zlib, gtk, and I'm probably forgetting a few other things that I did download), yet when I open Ipython and plot the recommended example plot([1,2,3]) all I get is the error "NameError: name 'plot' is not defined". Possibly, the things I downloaded did not go to the right directories. Does anybody know if this matters, and if yes, where should the files be located? Part of the problem also is that my computer skills are low, so I don't understand many of the terms used (such as "backends", for instance - what is it?). I would really appreciate it if somebody could tell me what I should try to do or point me to a step-by-step guide ! (I would really, really love to be able to plot data I generate on Python...)

Try "from pylab import *" before using the plot function.

[Matplotlib-users] hist() and semilogy
Hello -
I haven't been able to find any useful documentation about semilogy
and exactly how i can implement it into a Histogram. I'm simply trying
to create a histogram of a lot of data with a y-axis scaled
logarithmically. Specifically I am creating a pixel histogram of a
FITS image...for anyone who cares. Here is the code i've used to
create the histogram:
#! /usr/bin/env python
import Image
import pyfits
import numpy
import numarray
from pylab import *
#Open each image
Gim = pyfits.open('Gimage.fits')
#Create arrays of the data from each image
Garray = Gim[0].data
onedarray = []
xsize,ysize = Garray.shape
for x in xrange(xsize):
for y in xrange(ysize):
if Garray[x,y] >= -0.02:
if Garray[x,y] <= 0.6:
onedarray.append(Garray[x,y])
g_hist = hist(onedarray,bins=100)
axis([-0.05,0.65,1,9])
xlabel('Pixel Number')
ylabel('How Many of Each Pixel')
savefig('test_histPANDA.png')
show()
thanks!!

Re: [Matplotlib-users] speeding up imshow
Thank you for the suggestion. I now have the update time down to about 70 ms. When I run the code through the profiler, I see that each plot update requires a call to matplotlib.colors.Colormap.__call__, and each of these calls takes 52 ms, 48 ms of which is spent inside the function itself. This looks like it is the bulk of the delay, so if I can optimize the Colormap.__call__ function, the performance should be much improved. Unfortunately I cannot seem to get finer grained information about what exactly is taking so long inside this function. Can anyone provide any hints?

Re: [Matplotlib-users] saving PNG graphics on mac
Sorry I didn't chime in sooner, as I'm pretty sure i know exactly what the problem is, and I should have reported it a couple weeks ago when I found it. > Matplotlib aside, you might want to make sure you installed the > Unicode version of wxWidgets, and reinstall it if necessary. Actually, this is backwards -- I think the OP is using the unicode version of wxPython, and that's the source of the problem. The unicode version returns a unicode object from a FileDialog for a path. MPL can't deal with a unicode filename, and thus the error: Matplotlib backend_wx error cannot return std::string from Unicode object There are a couple solutions: 1) use the ansi, rather than unicode version of wxPython. 2) Patch MPL: a) convert the filename to a string before passing it off to MPL -- this is an bad kludge, as the Mac (and recent Windows, and Linux, and...) filesystem is unicode, and folks could have non-ansi characters in their filenames. b) Open the file with Python, and pass that into the MPL savefig method, instead of the filename. This is apparently slow with older MPLs, but has been fixed for good performance in SVN. However, I think I tried this on the Mac, and it worked great, but on Windows, I didn't get errors, but didn't get valid PNGs either. I ended up going back to converting my filename to a string and passing that off to MPL. See: http://www.nabble.com/unicode-filenames-and-MPL.-to16318069.html#a16318069 For more discussion.
