Using Symbol font

[Steven van Dijk]

Hi,

I want to put an epsilon in my plot. I try to do this using "set term post
eps enhanced" and using "{/Symbol \145}" in the text of my key.

This does indeed produce an epsilon, but it is not in italics form. I want
it to look exactly like Latex produces it when you use $\varepsilon$. Also,
I do not want to use TeX inside Gnuplot, I want to know how to do it in
Postscript.

Can anybody help me?

TeX is not using "symbol", it is some computer modern font
(probably). Take a look at your TeX output and see if you can figure
out what font it is using. (dont ask me how to use it in gnuplot though!)

Normally, you'd be right, except that I use the mathptmx package (for Times
fonts). If I make postscript of the following Latex input:

\documentclass{article}

\usepackage{mathptmx}

\begin{document}
\pagestyle{empty}
$\varepsilon$
\end{document}

I see in the file.ps:

%%DocumentFonts: Symbol

At the end, I see what I assume produces the epsilon:

TeXDict begin 39158280 55380996 1000 600 600 (testing.dvi)
@start /Fa 154[36 101[{.167 SlantFont}1 83.022 /Symbol
rf end

and

1 0 bop 639 523 a Fa(e)p eop

I can make heads, but not tails of it. I do not know how to put this
postscript in a gnuplot label.

ok, there is no italic version of the symbol font, so they
are making one up by slanting the base font (a bit of a hack..)
To use this you need the entire TeXDict do define the SlantFont
function. Try asking on comp.lang.postscript or the Tex groups,
maybe somebody knows how to reverse engineer the TeXDict..
