PyX

Dear Michael,=20

Thank you for the tips. I need the new line feature, so I chose the first o=
ne:

Unfortunately I got error messages again:

1. The simplest version works:

>>> c =3D pyx.canvas.canvas()
>>> c.text(0, 0, r"1st Dec  1997", [pyx.text.parbox(4.0)])=20
>>> c.writeEPSfile("Figure_1")
OK

2. \\ (new line) does not work:

>>> c =3D pyx.canvas.canvas()
>>> c.text(0, 0, r"1st Dec \\ 1997", [pyx.text.parbox(4.0)])=20
TexResultError: unhandled TeX response (might be an error)
The expression passed to TeX was:
=2E.. *! Argument of \\ has an extra }.

3. \textsuperscript does not work either:

>>> c =3D pyx.canvas.canvas()
>>> c.text(0, 0, r"1\textsuperscript{st} Dec  1997", [pyx.text.parbox(4.0)]=
)=20
TexResultError: unhandled TeX response (might be an error)
The expression passed to TeX was:
=2E.. *! Undefined control sequence.

Where am I wrong?

Thanks so far

Actually I wasn't aware of the "[pyx.text.parbox()]" feature!  I always=20
use inline latex like this:

   c.text(0, 0, r"\parbox{4em}{test \\ second line}")

This works for me also in labels etc...  There was a thread on a related=20
topic a few days ago, you might want to have a look at that in the archiv=
e.

Thank you, this lead to the solution of my problem. I had to include the li=
ne:
>>> pyx.text.set(mode=3D"latex")

The difference between them I observed now was that "[pyx.text.parbox(4.0)]=
"=20
version indented the first line, while yours did not.

Thank you
