[Matplotlib-users] How do I disable antialiasing on imshow with wxagg backend ?
I know I should find this in the documentation, but I am finding all kinds of bells and whistles about the interpolation and the fancy agg features except how to disable antialiasing .

[Matplotlib-users] Label & ticks spacing
Hi, all how to change the spacing between axes and ticks labels, ticks labels and axes labels? I mean vertical spacing for X axis and horizontal one for Y.

See these parameters from your matplotlibrc file: http://matplotlib.sf.net/matplotlibrc xtick.major.pad : 4 # distance to major tick label in points xtick.minor.pad : 4 # distance to the minor tick label in points ytick.major.pad : 4 # distance to major tick label in points ytick.minor.pad : 4 # distance to the minor tick label in points >From code, you can also control the pad with, for example, for tick in ax.xaxis.get_major_ticks(): tick.set_pad(6) ditto for the yaxis and minor ticks..

When you say antialiasing, do you mean interpolation? AFAIK, antialiasing doesn't really come into play on the images. Perhaps what you want is ax.imshow(nx.mlab.rand(10,10), interpolation='nearest') JDH - Using Tomcat but need to do more? Need to support web services, security?

The Axis labels are automatically placed to be below (or to the left of) the tick labels. So it may be enough to simply set the pad. JDH - Using Tomcat but need to do more?

[Matplotlib-users] How do I take off the gray border padding from a figure ?
Hi:
Thanks for you last reply John you where right on.
Yet another newbie question, how do I take off the frame off ?
I have tried frameon=False, and played with the figsize and dpi, and I
just can't get rid of the gray (or white) border around my image. I want
the image to expand to take on the whole sizer I can't afford the
padding on the side.
This is how I am adding my image to the figure:
(I don't know if I should be using add_subplot(111) ? )
figure = Figure()
self.axes = figure.add_subplot(111)
self.axes.imshow(self.image, interpolation='nearest')
self.axes.axis('off')
Thanks.
Daniel.

[Matplotlib-users] C library problems on Windows: Enthought python 2.4.3 and matplotlib 0.87.5
For my Windows XP machine, I downloaded enthon-python2.4-1.0.0.exe and matplotlib-0.87.5.win32-py2.4.exe. I installed python first (it's version 2.4.3) via the Enthought executable; it installed fine with no errors. Then matplotlib installed fine with no errors. I installed the matplotlib_examples_0.87.1.zip examples and tried to run the barchart_demo.py script; here's the error message I got: RuntimeError: module compiled against version 102 of C-API but this version of numpy is 90907 The import of the numpy version of the nxutils module, _nsnxutils, failed. This is is either because numpy was unavailable when matplotlib was compiled, because a dependency of _nsnxutils could not be satisfied, or because the build flag for this module was turned off in setup.py. If it appears that _nsnxutils was not built, make sure you have a working copy of numpy and then re-install matplotlib. Otherwise, the following traceback gives more details: Traceback (most recent call last): File "barchart_demo.py", line 3, in ? from pylab import * File "C:\bin\PYTHON~1\Lib\site-packages\pylab.py", line 1, in ? from matplotlib.pylab import * File "C:\bin\PYTHON~1\Lib\site-packages\matplotlib\pylab.py", line 198, in ? import mlab #so I can override hist, psd, etc...

Any ideas on how to address this > problem? Enthought includes matplotlib, so you dont need to install it seperately. The reason for the problem is that your enthought executable includes an older version of numpy and matplotlib. The newest matplotlib is compatible with numpy1-0b5 and later.
