key box too large using subscripts in postscript enhanced mode
Dipl.-Ing. A.Manthey
When I am using "set term post enhanced" and name a plot like:
"x_{/Symbol s}"
then the box around the key becomes too large. Obviously the length
of the box is computed from the length of the string which leeds to
a length of 13 characters (!) instead of something around
1.5 characters.
I am using:
G N U P L O T
Linux version 3.5 (pre 3.6)
patchlevel beta 347

Has anybody managed to get around this bug?

Yes. There's an option called "width" on the "set key" command, added
for precisely this reason. I think it was included bybeta 347 -- if not,
you'll need to get the official release of 3.7.
"help set key" says, in part:
Syntax:
set key { left | right | top | bottom | outside | below
| <position>}
{Left | Right} {{no}reverse}
{samplen <sample_length>} {spacing <vertical_spacing>}
{width <width_increment>}
{title "<text>"}
{{no}box { {linestyle | ls <line_style>}
| {linetype | lt <line_type>}
{linewidth | lw <line_width>}}}
[snip]
The <width_increment> is a number of character widths to be added to or
subtracted from the length of the string. This is useful only when you are
putting a box around the key and you are using control characters in the text.
`gnuplot` simply counts the number of characters in the string when computing
the box width; this allows you to correct it.
