gnuplot - Remove "empty space" in splot with log scaled z axis -


i have gnuplot script generates surface plot data. i've scaled z axis logarithmically, such in example on gnuplot.info1 - , in example, lot of empty room @ "bottom" of plot.

in example, ticks on z axis end @ 1, axis doesn't end there - origin of plot further "down" (in z direction).

how set origin data starts? dynamic approach (that's not dependent on me knowing data set in advance) preferred, if it's possible.

1 follow link , search page "surfaces z log scale" find relevant example.

this not obvious one, (as usual) there setting that. try

set xyplane 1

and

help set xyplane

for more details.
