[Matplotlib-users] matshow
Friends,
I have a matrix data and i used matshow() function to plot. The plot is
attached.
1) After plotting the data, i used xticks() function to change the x-axis
tick labels from x1 to x12 ( figure attached). Similarly I want to change
the y-axis tick labels into as A,B and C, instead of 0,1,2 (in the attached
figure) but when i use yticks() function as below, it dosent happen, instead
it changes the plot.
yticks( arange(3), ('A','B','C'))
2) I used the colormap *cm.autumn* to create the plot. Suppose if i want to
generate the same plot with green,black, red combination, how should i
specify the colors in matshow.
Thanks in advance.

Re: [Matplotlib-users] mplot3d bars3d demo
The bug was fixed on the 0.99.x branch, not in 0.99.0 (which predates the fix). The fix should, however, make it into the forthcoming 0.99.1 release.

Re: [Matplotlib-users] Polar plots rendered incorrectly in SVG
Thanks. I think you're right, Jae-Joon. I've committed a slightly
simplified version of your patch on the 0.99 branch and trunk.

Thanks for reporting the problem.
I can reproduce this error in the svn trunk.
My diagnosis is that this is because the clip mask is not correctly
set, i.e., the mask path is not properly flipped in the svg backend.
I was able to solve this particular problem using the attached patch.
But, i'm not sure if this patch is a general solution. So, I hope
other developers step in.
Bartosz, below is a workaround you may use meanwhile. Note that the
workaround will give correct result only for svg backend.
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_axes([0.4, 0.4, 0.25, 0.25], polar=True)
# modify the ax.patch transform to work around with svg backend bug
import matplotlib.transforms as mtransforms
flipped_transAxes = mtransforms.BboxTransformTo(ax.bbox) \
+ mtransforms.Affine2D().scale(1.0,
-1.0).translate(0., 72*fig.get_figheight())
ax.patch.set_transform(flipped_transAxes)
ax.xaxis.set_clip_path(ax.patch)
ax.yaxis.set_clip_path(ax.patch)
theta1 = np.pi/4
ax.plot([theta1, theta1], [0, 1], '-')
plt.savefig('test_polar.svg')
plt.savefig('test_polar.png')

Here is an example reproducing this error:

[Matplotlib-users] saving an axes to draw in a different figure
I'm trying to draw the axes from one figure directly over the axes for
another figure, in a sense, combining the two axes as two layers on one
figure.
So, first I get an axes instance, ax.
import matplotlib.pyplot as plt
fig=plt.figure()
fig.add_subplot(111)
plt.plot(range(10), [i^2 for i in range(10)])
ax=fig.axes[0]
plt.savefig('test.png')
Okay, now I have the axes ax. I want to draw ax directly on top of
the following figure, and get a result that would be the same as if I
had called the plot command above directly in the following code. All
I'm passed in my real code is the newax variable below, which is why I
use newax.get_figure()).
fig=plt.figure()
newax=fig.add_subplot(111)
ax.set_figure(newax.get_figure())
newax.get_figure().add_axes(ax,label=newax)
plt.savefig('test2.png')
However, the result of test2.png is not very pretty and definitely not
what I want. The tick labels for the y-axis are all scrunched up, for
example.
Can anyone help?
For those curious, what I'm doing is working on getting the Sage
graphics code to be able to wrap and intelligently display matplotlib
axes objects, so that a person could easily create a matplotlib axes,
wrap it in the Sage graphics class, and then be able to manipulate it in
Sage. In order for this to work, it seems like I need to save the axes
object I care about, and then when Sage composes it's final figure
(using matplotlib), it passes me an AxesSubplot object. I need to
somehow take that subplot object and draw my saved axes on it in the
most intelligent way possible. In the code above, I try taking the
given AxesSubplot object, getting the figure from that, and then just
adding my saved axes to that figure. Is there a better way to do this?
Thanks,
Jason

Re: [Matplotlib-users] tk_agg plotting error when using legend()
This turned out to be a bug in the legend code. This is now fixed in the maint. branch and the trunk. Adam, Do you want these vertical lines show up in the legend? If not, the easiest workaround is to use some garbage label which starts with _, i.e., vlines(3e10/6000e-8,1e-7,1e-4,linestyle='--', label=_nolabel) If you want, you may use axvline or plot instead, which creates a Line2D instance (instead of LineCollection) which will work fine with the legend.

[Matplotlib-users] axes3d material in matplotlib-0.99.0.win32-py2.5 missing?
unless I'm misunderstanding something, the website says that
matplotlib-0.99.0.win32-py2.5
should contain the axes3d material. It doesn't. Instead, it axes3d.py
contains the following:
raise NotImplementedError('axes3d is not supported in matplotlib-0.98.
You may want to try the 0.91.x maintenance branch')
note that I am on a Windows machine and I'm not sure I can build
everything from the trunk.
thanks in advance.

It looks like you are having tow problems -- first, you apparently
installed a new matplotlib over an old matplotlib and so there are
some old files laying around. Blow away site-packages/matplotlib and
reinstall. See
http://matplotlib.sourceforge.net/faq/installing_faq.html#cleanly-rebuild-and-reinstall-everything
Secondly, you need to be importing mplot3d from mpl_toolkits, it's new
location. You appear to be importing it from matplotlib.axes3d, it's
old location which is now deprecated. Eg see
http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/tutorial.html
Hope this helps,

[Matplotlib-users] violin plots
Flávio Coelho has implemented Violin plots for MPL. Nice! He has a question regarding its suitability for inclusion due to a dependency on scipy for the gaussian_kde function. http://pyinsci.blogspot.com/2009/09/violin-plot-with-matplotlib.html Is there a place this could live in the MPL code base without requiring scipy? Perhaps we should just include it as a demo. I note that examples/pylab_examples/demo_agg_filter.py requires scipy, too. Thanks Flávio for sharing -- I have occasionally wondered how my data would look in a violin plot. -Andrew -- Come build with us!
