Yes. Use interpolation='nearest' instead.

Running the test script below gives me the image I have attached, 
which looks like it has been smoothed.
Does imshow perform some sort of smoothing on the data it displays? 
If so, is there a way to turn this off?
#!/usr/bin/env python
from pylab import *
data = array([[1,2,3,4],[5,6,7,8]])
imshow(data,interpolation=None)
savefig('output.png')

Are you using the CocoaAgg backend or MacOSX? If the former, is the
latter an option for you?

I'm not sure if you have the option to go 32-bit, but the cocoa
backend works fine on snow leopard with a 32-bit build (-arch i386),
that I built on leopard prior to upgrading. The 64 bit transition
should be interesting, especially given the persistence of heritage
universal (PPC) build processes.

I'm very, very sorry to bump my own thread, but I'm in a bit of a 
pickle. Matplotlib installs and runs nicely on my Snow Leopard 
installation, but I'm "blind": cocoa fails, wxpython is 32b only and 
compiling Qt4 is becoming increasingly frustrating on a 64b machine.
Any help or hint would be really, really appreciated.

The first thing you are doing wrong is failing to provide a complete, 
minimal, self-contained example illustrating the problem. I don't think 
the snippet you gave is representative of what you are running. Instead 
of "map" I think you mean "zip". Where are you incrementing "i"?
The general approach of using the get_facecolor() method to get the 
array, and indexing into it, is fine. That is not where the problem is. 
 Once you put together a minimal example, I think you will find the 
problem--or that there really is no problem.
A collection is used by scatter because it is much more efficient than a 
sequence of objects.

John,
The following code works for me (Python 2.5.4, Matplotlib 0.99):
# create and format the colorbar
cbar = pl.colorbar(G, ticks=range(g1,g2+1)) 
cbar.ax.set_ylabel('Gradient (%)', fontsize=10)
cl = pl.getp(cbar.ax, 'ymajorticklabels')
pl.setp(cl, fontsize=10)

Hello,
I'm trying to plot text objects with the color used in m.scatter. My goal is
to individually label each scatter object. I've tried the following:
circles=m.scatter(cx,cy,zsize,zlevel,cmap=cmap)
and then:
CC = circles.get_facecolor()
i=0
for x,y in map(cx,cy):
 ax.text(x,y,'some text', color=CC[i])
But if fails because:
m.scatter returns:
<matplotlib.collections.CircleCollection object at 0x127898d0>
Rather than a list of objects??? Or something. The point is, I would expect
'circles' above to have len==cx, but it does not. What am I doing wrong?

You should be able to do that for most of numerix I believe (I and would
definitely try that first).

Hi there,
I want to move to numpy only. What would be the replacement for:
from matplotlib.numerix.mlab import amax
?
Many thanks in advance,
Alan

Could someone please explain how to change the font properties for a colorbar
tick label, the following causes no error, but it does NOT work:
 ## CREATE COLORBAR 
 ## make a copy of the image object
 im2 = copy.copy(im)
 im2.set_cmap(colmap)
 ## create new axis for colorbar.
 cax = plt.axes([l+w+0.03, b, 0.025, h-0.035])
 cb = plt.colorbar(im2, cax)#, format='%3.2g') # draw colorbar
 ## set colorbar label and ticks
 p_cax = mpl.font_manager.FontProperties(size='6')
 clabels = clevs[::10] ##clevs, by 10 steps
 clabels.append(clevs[-1]) ## add the last label
 cb.ax.set_yticks(np.linspace(0,1,len(clabels)))
 cb.ax.set_yticklabels(['%3.2g' % cl for cl in clabels],
 fontproperties=p_cax)
 cax.set_title('sensitivity\n(%s)' % units,
 fontproperties=p_cax)
NOTE: It does set the title properties correctly.

Hi there,
In mtpl __version__ = '0.98.5.3' "from matplotlib._cm import LUTSIZE"
still works, but in matplotlib.__version__ = '0.99.0' no:
from matplotlib._cm import LUTSIZE
ImportError: cannot import name LUTSIZE
How can I replace/solve this issue?
Many thanks in advance.
Alan

The 0.99.1 release is available for download from sourceforge
 http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-0.99.1/
This is a bug-fix release with an emphasis on stability. Lots of bugs
have been fixed since 0.99.0 so thanks to all who contributed bug
reports, patches and fixes. A detailed listing of fixes is available
in the svn log below
Thanks to Christoph Gohlke for the windows builds.

Does Pydev have any sort of specific support for matplotlib? I'm asking
because even in the normal Python shell interactive work can be
difficult, depending on the backend, and whatever command-loop magic
IPython does makes it work better. You could try different backends, but
I suspect that Pydev would have to have specific support for integrating
the backend-specific command loop for it to really work.

Hello list,
I recently started using Eclipse with Pydev. I like it a lot but have not
been able to get interactive plotting going (which otherwise works fine).
My file is simple:
from pylab import *
ion()
plot([1,2,3])
When I run this form within Eclipse, I do see a graphing window open up but
then it disappears again when it is done, before I can even look at it.
Any suggestions on how to keep the graphing window open?
Thanks,
Mark

Your code works as expected with the current svn head. If you're using
older version of mpl, can you try to update and see if it solves the
problem?
If you're using recent version of mpl, please post an error message you got.

matplotlib basically creates a vector-based plot, and a notion of
"single-pixel" is not very meaningful. While it makes some sense for
raster output formats like png, but still, the result depends on the
dpi of your output. Note that unit for the parameter "s" in the
scatter function is in points(**2). 1 points corresponds to one pixel
in dpi=72. With higher dpi, the scatter points will occupy more than a
single pixel.
