[Gnuplot-info] how to change the canvas size of eps file

[Jon <dev...@gm...>]

Dear All,

I had problem with creating an eps file differing from the default canvas
size. I used the following command, which partially does the job, but it
seems I have to scale all other size dependent quantities as well to
maintain the relative ratio, which is too troublesome. I am sure there must
be better way to do it,

The following are my sample code

set macro
ratio = "2"
set size @ratio,@ratio

set term postscript eps enhanced color solid
set out 'aaa.eps'
set multiplot
set size 0.475*ratio,0.475*ratio
set origin 0.025*ratio,0.025*ratio
set tmargin 1;set lmargin 5;set rmargin 0;set bmargin 2.5  # did not change
to relative size
set label 2 at graph 0.05,0.925 'something' font "Times-Roman,15"
p ...
set origin 0.525*ratio,0.025*ratio
set tmargin 1;set lmargin 2;set rmargin 1;set bmargin 2.5
set label 2 at graph 0.05,0.925 'something' font "Times-Roman,15"  # did not
change to relative size
p ....
set origin 0.025*ratio,0.525*ratio
set tmargin 1;set lmargin 5;set rmargin 0;set bmargin 0
set label 2 at graph 0.05,0.925 'something' font "Times-Roman,15"  # did not
change to relative size
p ....
set origin 0.525*ratio,0.525*ratio
set tmargin 1;set lmargin 2;set rmargin 1;set bmargin 0
set label 2 at graph 0.05,0.925 'something'  # did not change to relative
size
p ....
unset multiplot
set out

The outcome is that the actual size of the canvas is controlled by ratio,
but font size, relative margins are still kept as if the size were default.
Any solution to that except for changing size everywhere?

Thanks,

Sincerely,
Jun
