Axis numbers

[Dieter Britz]

I am doing a multiplot, in which one plot sits above the other. I want
both x-axes to be the same length, but because the different y scales,
they are not. This is because the top y numbers are given as -1, 0, 1
and the lower ones as 0.0, 0.1, 0.2. I know I can force the top numbers to
be given as -1.0, 0.0, 1.0, using format, but what should this format be?
The gnuplot manual mentions "%g", but I can't find the details. If this
is in the manual, under what heading?

The other problem is the x-axis numbers. These go logarithmically from
10^{-4} to 10^4, and at the moment they are given as 1e-04, 0.001, ...
10000. What format do I use to get them in the exponential form, 10^x?

Thirdly, I want the x axis label as italic "T". There is mention of fonts
in the manual, but the only font I find other than the default, is
Helvetica. What font description do I use to get italics{T} ?

Thank you in advance for answers.

see e.g. http://t16web.lanl.gov/Kawano/gnuplot/tics-e.html:

set format x "10^{%L}"

see e.g. http://t16web.lanl.gov/Kawano/gnuplot/plot2-e.html

gnuplot> set terminal postscript enhanced "Helvetica" 16
gnuplot> set title "Damping Function" font "Times-Roman,40"
gnuplot> set xlabel "X-AXIS" font "Helvetica,20"
gnuplot> set ylabel "Y-AXIS" font "Times-Italic,32"
gnuplot> plot exp(-x)

Nothing you could'nt have found in 2 seconds using google. ;-)

Leaving aside the issue of format statements, I am guessing that the
more important part of your question is how to make the axes line up
exactly. Please see the demo plot
