Hello,
I try to use LaTeX in my plot. I follow the instructions from http://www.scipy.org/Cookbook/Matplotlib/UsingTex
florian@...615...:~> cat .matplotlib/matplotlibrc
text.usetex : true
My plotting code looks like:
Ma = arange(1.0, 5.0, 0.01)
Ts = [T(i) for i in Ma] # BTW: Is there a way to spare this line?
plot(Ma, Ts, label=r'/frac{T2}{T1}')
Running the script gives:
python Stossverlauf.py --verbose-helpful
$HOME=/home/florian
CONFIGDIR=/home/florian/.matplotlib
matplotlib data path /usr/lib64/python2.6/site-packages/matplotlib/mpl-data
loaded rc file /home/florian/.matplotlib/matplotlibrc
matplotlib version 0.99.1.1
verbose.level helpful
interactive is False
units is False
platform is linux2
Using fontManager instance from /home/florian/.matplotlib/fontList.cache
/usr/lib/python2.6/site-packages/pytz/tzinfo.py:5: DeprecationWarning: the sets module is deprecated
from sets import Set
backend Agg version v2.2
and that's all, no plot window appears, the script is finished. If I remove the matplotlibrc everything works fine (of course no LaTeX).
I think all the necessary programs are in place:
florian@...615...:~> which latex
/usr/local/bin/latex
florian@...615...:~> which dvipng
/usr/local/bin/dvipng
florian@...615...:~> which gs
/usr/bin/gs
Any idea what could be wrong?
Thanks,
Florian

not sure what T is. you could try T(Ma); you can do that of course also
directly in the plot command
plot(Ma, Ts, label=r'/frac{T2}{T1}')
should be backslash and math mode:
plot(Ma, Ts, label=r'\\frac\{T2\}\{T1\}')
legend()
show()
and that's all, no plot window appears, the script is finished.
you did not show() !
best,
sebastian.

In addition to Sebastian's points, make sure your matplotlibrc is specifying an interactive backend (e.g. gtkagg, tkagg, wxagg, qt4agg) if you want the plot to appear on the screen.

not sure what T is. you could try T(Ma); you can do that of course also
directly in the plot command
T is a python function:
def T(Ma):
fp = fluidproperties.IdealGas()
fp.Ma = Ma
return NormalShock(fp).fp_out().T / fp.
plot(Ma, T(Ma), label=r'\\frac\{T2\}\{T1\}') does not work. The plot window appears, but no plot.
> plot(Ma, Ts, label=r'/frac{T2}{T1}')
should be backslash and math mode:
plot(Ma, Ts, label=r'\\frac\{T2\}\{T1\}')
legend()
show()

Actually I did it. I stripped the code before pasting it here, my fault. But not it works, thanks!
