pm3d epslatex axis labels too close to axes

[Gernot Hassenpflug]

Since I have been using the 4.2-rc4 version my epslatex output has
been much more reliable, thank you very much. Mr. Mikulik urged me to
post any perceived bugs, and since the OP in another thread has not
done so, apparently, I take it upon myself.

In epslatex mode, tick marks for the x and y axes are too close to the
axis lines, and often overlap these. Furthermore, the x-axis
lower-boundary mark may overwrite the z-axis lower-boundary mark.

Below is an example adapted from Mr. Matsuda's page.

A workaround for the unsightly spacing I can think of are:
1. specify axis tick marks explicity to avoid lumping
2. ensure no tick label for edges of axes

But I cannot see a way to control the spacing between the labels and
the axis.

Many thanks for any input,
Gernot Hassenpflug

I think that is a general problem in splot, not specific to the
epslatex terminal. The tic label offsets are ignored in 3D.
This should probably be fixed, but in the meantime you can work
around this by using the tic label format statement. For instance,
your example plot looks better if you add the commands

set format x "\n %g"
set format y "\n%g"

Sigh. Brain not working today.
The tic label offsets are not ignored in 3D. But the verical
offset is still "y", not "z". So to displace your
tic labels downwards, away from the axis lines:

set xtics offset 0,-0.5
set ytics offset 0,-0.5

Many thanks, that works fine for me.
