Empty space in ratio constrained gnuplot -

i trying create density plot constraint axis in gnuplot, have lot of empty space outside plot

reset set term postscript enhanced eps color set output "verif_thetak_60deg.eps" set pm3d map set size ratio -1 set xtics 0.5 set autoscale xfixmax rayon=0.35 set object 1 circle @ 0,5./2 size rayon front end fs empty border lw 3.0 set object 2 circle @ sqrt(3),5./2 size rayon front end fs empty border lw 3.0 set object 3 circle @ sqrt(3),0.5 size rayon front end fs empty border lw 3.0 set object 4 circle @ 0.5*sqrt(3),1 size rayon front end fs empty border lw 3.0 set object 5 circle @ 0.5*sqrt(3),2 size rayon front end fs empty border lw 3.0 set object 6 circle @ 0,0.5 size rayon front end fs empty border lw 3.0 splot "verif_thetak_60deg.dat" u 1:2:3 notitle

i have tried using multiplot set origin, working empty space circles rotated. not understand. help me? here first lines of sample data

i have allow blank line each time first column change.

at moment image looks this:

to margins , size right requires fiddling:

first must set canvas size improve fits shape of plot e.g. set terminal postscript eps size 2in,4in.

then must adjust lmargin and/or bmargin manually. requires iterations right.

as notice: upcoming version 5.0 has alternative set view map scale ... simplifies this.

alternatively can utilize tool epstool right bounding box:

epstool --bbox --copy --output cropped.eps original.eps
