Re: [sage-support] Re: Accentuated characters in axes_label
Maybe this is a lame workaround, but I save all my matplotlib plots as
eps and then run epstopdf. I actually call epstopdf through os.system
in a custom save function. I have never had a problem with latex and
saving eps.

Try replacing `dviread.py' with the latest version from matplotlib's
source code repository (svn trunk revision 8956 or later) and let me
know if this fixes your issue. This smells of the issue I was having
not so long ago. See here:

[sage-support] Re: Accentuated characters in axes_label
But this workaround seems to prevent me from saving the fig in pdf (or
svg):
File "/opt/SAGE/local/lib/python2.6/site-packages/matplotlib/
dviread.py", line 727, in _register
assert encoding is None
AssertionError
Here's the code:
# -*- coding: utf-8 -*-
from sage.all import *
import matplotlib as mpl
mpl.rcParams['text.usetex'] = True
plt = plot(sin, -pi, pi)
plt.axes_labels([ 'Valeur', r"\'{E}chantillon" ])
save(plt,filename='/home/maxim/test.pdf')
Same thing happens if I try to use pyplot instead.
Any clues or other ideas?
Thanks,
Maxim

[sage-support] Re: Accentuated characters in axes_label
Thanks Michael! That's a nice workaround. Should I open a ticket about it in trac? I haven't found this defect listed there already.

[sage-support] Re: Configuring sage at the bash prompt
I did a quick-and-dirty edit to the source in devel/sagenb/sagenb/ notebook/run_notebook.py, replacing the raw input for domain name with: import socket dn = socket.gethostname() Also replaced the body of get_admin_passwd() like so: def get_admin_passwd(): passwd = 'TopSecret' return passwd Seems to work fine for what we're doing; we assume anyone within our company's firewall is trustworthy. This way we can have operations write an init script that runs sage with the reset=True flag, then with the interface='' flag, and we're up and running.

[sage-support] braces in output of latex() command
Hi everyone, i use Sage for working with big expressions. To receive
observable output i use latex's package breqn that can automatically
divide the expression into several lines. But there is the problem
with latex() command. For example here is the code(in notebook):
#
var("a,b,c,d,f,g")
expr=(a - b)*f + (c - d)*g
latex(expr)
#
Output of this code is:
#
{\left(c - d\right)} g + {\left(a - b\right)} f
#
Breqn package can not divide expression into lines if it is included
ino braces { }. So, expression above can be automatically divided only
into two lines, like this:
{\left(c - d\right)} g + \\
{\left(a - b\right)} f
But, if the braces { } are removed, i.e
\left(c - d\right) g + \left(a - b\right) f
then the breqn package can divide this expression very well, for
example like this
(c - \\
d) g + \\
(a - \\
b) f \\
(Of course, it is just example, actual expression is more complicated)
#
Is it possible to remove braces { } from output of command latex()?
I.e. i want that the output of
#
var("a,b,c,d,f,g")
expr=(a - b)*f + (c - d)*g
latex(expr)
#
was
\left(c - d\right) g + \left(a - b\right) f
instead of
{\left(c - d\right)} g + {\left(a - b\right)} f
Help me please, i very need it.
P.S. Sorry for my rough english.

[sage-support] [ANN] New package: SpaceFuncs (2D, 3D, ND geometric modeling, optimization, solving)
Hi all, I'm glad to inform you about new, 4th OpenOpt Suite module: SpaceFuncs - a tool for 2D, 3D, N-dimensional geometric modeling with possibilities of parametrized calculations, numerical optimization and solving systems of geometrical equations. The module is written in Python + NumPy, requires FuncDesigner (and OpenOpt, DerApproximator for some operations). It has completely free license: BSD. For details see its home page http://openopt.org/SpaceFuncs and documentation http://openopt.org/SpaceFuncsDoc Also, you can try it online via our Sage-server http://sage.openopt.org/welcome Regards, Dmitrey. -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Hi Maxim,
The only solution I've found is to direct Sage's matplotlib to process
plot text with LaTeX:
#!/usr/bin/env sage-python
# -*- coding: utf-8 -*-
from sage.all import *
import matplotlib as mpl
mpl.rcParams['text.usetex'] = True
plt = plot(sin, -pi, pi)
plt.axes_labels([ r'Valeur', r"\'{E}chantillon" ])
plt.show()
Interestingly enough, the following does work with the Enthought
Python Distribution, but *only* if the `coding: utf-8' line is
included (and LaTeX is not handling plot text):
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt
from numpy import linspace, sin
t = linspace(-2, 2, endpoint=True)
plt.plot(t, sin(t))
plt.xlabel('Valeur')
plt.ylabel(u'Échantillon')
plt.show()
This even works with LaTeX processing when EPD's `matplotlibrc'
configuration file contains `text.latex.unicode = True'.
Hope this helps.
Michael
