xyplane tics too large with orthogonal splot views

[Dima K. <gn...@di...>]

Hi. I just made some 3D plots from an orthogonal side view (set view
90,0). This has special-case logic in gnuplot to treat it like a 2D plot
in some ways. It looks like the logic isn't completely right, though,
and the tics on the xy plane end up larger than they should. And the
tics appear on both sides of the plane, which isn't obviously right. Can
somebody please take a look?

This happens with the latest gnuplot in git.

The script appears below, and the result is attached.

Thanks!



set view 90,0
set xyplane at -0.1
set xtics 0.5
set ytics 0.5
set view equal xyz
set xlabel "x"
set ylabel "y"
set zlabel "z"

set terminal png size 600,1000
set output "/tmp/tics-too-big.png"
