key width

[John <aen...@ya...>]

Hi,

I'm using the pslatex terminal of gnuplot.
Everything works fine but the annoying thing is that the default key width is
proportional to the number of characters contained in the title. However, the
numbers of characters produced by the LaTeX code $\\delta=1$ (see code below)
are less and so everytime I have to adjust the key width by hand.
Is there a trick or a regular feature to deal with this problem?

Here is the gnuplot code
set terminal pslatex norotate
set output "out.tex"
set format xy "$%g$"
set key right bottom Left reverse spacing 2 width -3.5 box lw 0.5
plot [x=0:1] [0:1] "data.txt" title "$\\delta=1$" w l lt 1 lw 1
