[Matplotlib-users] Latex characters don't show when I save to eps
Hi, I have a strange problem with matplotlib: I use the greek character phi as a label ($\phi$). When I display the diagram everything looks fine, only when I save to an eps file, the phi dissappears (emplty space instead). Some other characters (\mu, \Delta) don't have this problem. Does anyone have an idea what the problem could be?

[Matplotlib-users] loglog plot
Hi, I have a few questions about the loglog plot : 1- Is there a way to a have axis format with real numbers rather than numbers with exponent ? 2- I would like to have a grid not only for 10^2, 10^3, 10^4, 10^5 ... but also for the minor axis ticks. is it possible ? 3- I use loglog to plot parallel lines. How can I have the function label directly displaid next to the plotted straight lines ?

[Matplotlib-users] plotting traces scrollable window
Hi all, Few days back i came to know about python-matplotlib module when looking at segypy(seismic data processsing) python module.It uses pylab.plot(x,y...) to plot traces. But the issue is it plots the complete dataset in a single view.I would like to have plots with decent intervel and have scorllbars.Is there anything do be done with our matpplotlib functions ? If it is irrelevant to matplotlib (rather something to be done with segypy trace processing ) ,kindly ignore this mail / guide me in right way. -- Yours, S.Selvam -- Come build with us!

Re: [Matplotlib-users] Latex characters don't show when I save to eps
I can't reproduce this here, but your settings may be different than mine. What rcParams have you specified in your matplotlibrc (in particular, is usetex on or off)? What version of matplotlib?

Re: [Matplotlib-users] Latex characters don't show when I save to eps
The simplest case would be:
import pylab
pylab.plot([1,2])
pylab.xlabel("$\phi$")
pylab.savefig("fig.png")
pylab.savefig("fig.eps")
The png has the xlabel as phi, the xlabel in the eps file is just empty.
I use python 2.5, don't really know which version of matplotlib is installed
but it is not older than a year.
Here the latex part of matplotlibrc:
### LaTeX customizations. See
http://www.scipy.org/Wiki/Cookbook/Matplotlib/UsingTex
#text.usetex : False # use latex for all text handling. The
following fonts
...
#text.latex.unicode : False # use "ucs" and "inputenc" LaTeX packages for

Re: [Matplotlib-users] error locating backends module
Hello,
thank you for the respone. I am not working in such a file. I am experiencing
strange behaviors when trying to import matplotlib. The error message
"AttributeError: 'module' object has no attribute 'backends'" seems to appear
depending upon how I import matplotlib.
For example my wxApp is a simple frame holding a canvas and figure and a
matplotlib toolbar. My canvas is a subclass of matplotlib's canvas and my
figure is a subclass of matplotlib's Figure, my subclass modules are called
myCanvas and myFigure.
the wxApp module import as follows:
import matplotlib
import myCanvas
the myCanvas module imports as follows:
import matplotlib
import myFigure
the myFigure module imports as follows:
import matplotlib
matplotlib.use('WXAgg')
matplotlib.interactive(False)
matplotlib.backends.backend_wxagg._use_accelerator(True)
In this case the error occurs in the myFigure module where I call
use_accelerator:
"myFigure.py", line 19, in
matplotlib.backends.backend_wxagg._use_accelerator(True)
AttributeError: 'module' object has no attribute 'backends'"
If I comment out the call to use_accelerator, I get this message:
AttributeError: 'module' object has no attribute 'figure' and this occurs at
the start of my subclass "class Figure(matplotlib.figure.Figure)"
Now everything works just great if in the wxApp module I do the following:
import matplotlib
from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg
import myCanvas
I can wrestle my way through this so that it appears to work ok. However I
would prefer to understand what is happending and code this properly.
Also,
(1) I am not sure whether I need to call matplotlib.use('WxAgg') or if it is
implied when I import the WxAgg backend.
(2) what is the accelerator
(3) do I need to call matplotlib.interactive(False) in each module using
matplotlib?
thanks for the help!

Hi Jeff,
You don't happen to be in the same directory as a folder called 'matplotlib'
when trying to import matplotlib.backends, do you? If so, try moving to a
different directory before invoking python and importing matplotlib.backends.

any of the packages located in the matplotlib installation folder.
I just downloaded the latest matplotlib and installed it on a brand new
machine that is running vista. I'm running python 2.6.
how do I fix this problem?

Can you send the output of

It's possible this is a bug that has already been fixed in the
development version, but I'd like to confirm that by running the same
version that you have.

You can check formatting options from

You can use plt.yticks() to get new ticks as well as grids. Do you know how
to make ticklabels like 5x10^2 etc...? This I couldn't figure yet.

[Matplotlib-users] Polar plots rendered incorrectly in SVG
Dear all,
I have a problem with exporting polar plots to SVG. When attached to
axes which are not centered in the figure, the content (grids, data,
etc.) seems not to be shifted correctly with the axes. However, when I
plot it directly to the screen or export to PNG everything is fine.
Here is an example reproducing this error:
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)
theta1 = np.pi/4
ax.plot([theta1, theta1], [0, 1], '-')
plt.savefig('test_polar.svg')
plt.savefig('test_polar.png')
plt.show()
I was able to reproduce the problem it in matplotlib 0.99.0 (Backend:
GTKAgg).
Cheers,
Bartosz

Re: [Matplotlib-users] Polar plots rendered incorrectly in SVG
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')

This tutorial should help you get started: http://docs.scipy.org/doc/scipy/reference/tutorial/ndimage.html The section on "segmentation and labeling" will be particularly useful for you.

Re: [Matplotlib-users] mplot3d bars3d demo
I have reported that issue on the tracker at the end of July. You can fin dit here: http://sourceforge.net/tracker/?func=detail&atid=560720&aid=2830483&group_id=80706 It's supposed to be fixed in 0.99... are you sure you are using it? I remember trying it just after the bug was closed with an svn version and it was working. But then again I just tried it (0.99.0) and I get the bad behaviour... You seem not to be the only one! Maybe the issue should be re-opened. 2009/9/16 Sammy Yu > Hi, > I've been playing around with mplotlib's 3d charting functionality. > I wanted to generate something similar to this example: > > http://matplotlib.sourceforge.net/plot_directive/mpl_examples/mplot3d/bars3d_demo.py > > However, the number on scales are off (see attached).

[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.
Bala
