Font sizes and positioning of key, label and title?
Anton81
I'm preparing plots for a latex document, however I'm still struggling
with the layout. I use
graph.gnu:
set term epslatex color "phv" 8
set output "graph.tex"
file.tex:
\input{graph}
and the latex, dvips, ps2pdf route to create a pdf file (pdflatex
complains that file "graph" is not found)
Is this correct?
Now spacings and font sizes are not OK. First of all the pdf output
doesn't seem to care about the font size (only character size as a
unit in offsets seems to change)? :(
How can I change the font size of the "key" individually, as it turns
out to be too space consuming?
The positions of labels I adjust with 'set label "" offset ...' and
the spacing between multiplot graphs with 'set lmargin ...; set
rmargin ...'? However when changing fonts this hard-wired changes will
screw up again.
In principle I should be able to scale tics with "set tics scale ..."
and change the title font with 'set title ... font ...', once the font
sizes will work? Is that right?

Does it work when you use the postscript eps terminal? The few times
I've used epslatex, I've had problems, too. Despite Ethan's comments
above, I am very happy with using the eps terminal for basically
everything, including plots to be included in LaTeX. (I should say that
I don't want to criticize epslatex, as I never made a real effort to
figure it out.)

In the eps terminal, key has a font option. Don't know if it works with
epslatex. I guess you could always edit the tex output manually.

I don't know of a way to prevent this. Probably you should decide on a
font size before fine-tuning the rest.

I think so.

(enhanced eps) together with fixbb. If you like to use the latex
terminal (which gives a nicer typesetting for axis labels etc. within
the plot of course), a good idea is to write a little latex file to
make an eps beforehand. Just implement your figure there and create an
empty page (\pagestyle{empty} in the header and \thispagestyle{empty}
right after \begin{document} in the tex file). Then use
latex foo.tex
dvips -E -o<figurename.eps> foo.dvi
fixbb figurename.eps
This gives you a nice eps file which you can use nicely in your large
document.
With the epstopdf latex package you can also use pdflatex on the fly.
You have to call
pdflatex --shell-escape file.tex
then.

Hmm? In "set term" or "set key"? I couldn't find it.

Which version of gnuplot do you have? I have 4.3, compiled from cvs.
"help key" gives the following:
set key {on|off} {default}
{{inside | outside} | {lmargin | rmargin | tmargin | bmargin}
| {at <position>}}
{left | right | center} {top | bottom | center}
{vertical | horizontal} {Left | Right}
{{no}reverse} {{no}invert}
{samplen <sample_length>} {spacing <vertical_spacing>}
{width <width_increment>}
{height <height_increment>}
{{no}autotitle {columnheader}}
{title "<text>"} {{no}enhanced}
{font "<face>,<size>"} {textcolor <colorspec>}
{{no}box { {linestyle | ls <line_style>}
| {linetype | lt <line_type>}

Oh I see. On my work laptop I have 4.2pl3
I should try the newer version.
Thanks!

This is because pdflatex does not support eps graphics (only pdf and
png). Perhaps the easiest way to go is (as someone else suggested) to use
the `epstopdf' LaTeX package, which converts eps graphics to pdf on the
fly. An alternative is to call the `epstopdf' script (which should be
included in your LaTeX distribution) from your Gnuplot script via the
`system' command.

It seems that you are specifying a font size for the epslatex terminal
explicitly. To quote from the manual:
"When not using the standalone mode the actual LaTeX font and font size
at the point of inclusion is taken, so use LaTeX commands for changing
fonts."
I've found the best way to go is *not* to specify a font size and do
exactly as it says above: use LaTeX commands for changing fonts. Then you
simply treat all text in your plot - labels, key, etc. - as if it were
LaTeX text (because it is!).

Hmmm... you can specify a font/size for the key, but I'm not quite sure
how this interacts with LaTeX.

Not quite sure what you mean here.

Again, I suggest you'll find this all to be a lot smoother by letting
LaTeX handle fonts (i.e. by using LaTeX rather than Gnuplot for all text
manipulation). You might well find it necessary to mess about with
offsets, margins and spacing to get text placement to look good (I
suspect that this is because there is a limit to what Gnuplot can "know"
about how LaTeX will size and place text), but a little experimentation
does the job. In my view it's worth the minor hassle, as results tend to
look very, very good. In particular you maintain consistency with your
document's fonts and have all of LaTeX's considerable maths typesetting
capabilities available right there in your plots.

Further to this, looking back on some old code it seems I've used this
workaround: input your epslatex `myfig.tex' with e.g.:
\begin{figure}
\begin{footnotesize}
\input{myfig}
\end{footnotesize}
\end{figure}
Then all text specified in the figure - including the key - defaults to
footnotesize. Any text in your figure that you want to be some other
size, you then specify explicitly via Gnuplot using LaTeX markup; e.g.:
set xlabel "{\normalsize label text}"
