EPS with TeX

D2Hitman · August 12, 2009, 11:13am

Hi,

I am trying to use a text label with a new line in the middle and then save
the figure to .eps

text(0.5, 0.5, r'a \\ b')
savefig('test.eps')

This results in:

Is it a problem that it is using pdftex instead of pslatex?

Can anyone offer any assistance? Cheers.

Yes.

i don't think so.

the example

from matplotlib.pyplot import *
text(0.5, 0.5, r'a \\ b')
savefig('test.eps')

runs without error here -- and latex is calling pdftex:

$ latex -v

could the OP perhaps post some more information?

Ok, I shouldn't have posted before my first cup of coffee. Thank you

the example was not fair though as it wasn't using latex... this one is now:

from matplotlib import rcParams
params = {'backend': 'ps',
          'text.usetex': True,
          'ps.usedistiller': 'xpdf',
          }
rcParams.update(params)

from matplotlib.pyplot import *

text(0.5, 0.5, r'a \newline{} b')
savefig('test.eps')

it does not crash (the version with '\\' does) but does not produce a
line break, either...

best,
sebastian.

text(0.5, 0.5, 'a \n b')

works.

Yes.

I am trying a few things in matplotlibrc, but cannot change from pdftex...

Is there something obvious i am missing? If so what?

Cheers.
