Dear Kostas,

You can put pstricks code into a label command, which provides text
rotated by quarter-turns, as in:

label(P(0,0), P(-4,0), "\\rotateleft{Vertical axis}", l);
                  ^                                   ^
Notes:           (1)                                 (2)

(1) Shift label left 4 points
(2) (Lowercase ell) Put label to the left of (0,0)

You must \usepackage{pstcol} in LaTeX to compile the resulting figure.
(The "elaps" script uses pstcol automatically.)

The upper right sample at
  http://mathcs.holycross.edu/~ahwang/software/images/index.html
illustrates the result.

Probably there are robust ways of rotating text by an arbitrary amount,
though I don't know offhand how to;  pstricks allows text to be typeset
along a path, but ePiX and pstricks don't use the same coordinate system
so specifying a "path" in a way meaningful to pstricks is likely to be
inconvenient. ePiX is undergoing a substantial redesign, and features like
rotated text will be easier in the fairly near future.

Hope that's helpful.

Best regards,

Andy

P.S. It's funny you should ask this: it occurred to me only two days ago
that rotating labels is possible. :)
