[Gnuplot-info] setting SVG viewbox to auto-calculated margins

[Grothausmann, R. Dr. <gro...@mh...>]

Dear mailing list members,


Is there any way to set the SVG viewbox to the auto-calculated margins after 
plotting?
Or any other way to get an SVG with all margins set to 0 BUT not losing 
everything outside the margins like annotations?
I tried:

set terminal svg
set lmargin 0
set rmargin 0
set tmargin 0
set bmargin 0
set xlabel "test"

but the output SVG does not contain any text/elements outside the margins.
When not setting the margins to 0, and adjusting the viewbox of the SVG 
afterwards (with the border coords found via inkscape) works, but I can't find a 
way to get the auto-computed margin values to e.g. create a sed-command that 
adjusts the viewbox accordingly after gnuplot finished.

I checked
show variables all
for variables containing fitting values. GPVAL_TERM_XMIN fits viewbox-x and 
GPVAL_TERM_XMAX-GPVAL_TERM_XMIN fits viewbox-width;
GPVAL_TERM_YMAX-GPVAL_TERM_YMIN fits viewbox-height but GPVAL_TERM_YMIN does NOT 
fit viewbox-y.
I could find no other value in the list that would fit or allow to calculate the 
correct value for viewbox-y as later found via inkscape.

Any help or hints are very much appreciated
