z2 axis in 3D plots

[Marcus Schweizer]

Hi,
using splot with set surface and set contour both
how can I manage to get the z-axis mirrowed to the
other corner. How can I repeat the z-values at the
z2-axis. I only found out that the tics can be copied
with set ztics mirrow. I know that I can set the
z-values by hand using the set label command and that
the z2-axis can be created with something like
splot [t=0:400000] 12,12,t. I'd like to know if there
is a more convenient way.

cheers

Marcus

To give the rough, short answer first: there is no such thing as a
'z2' axis in gnuplot. Space for it has been reserved in anticipation,
but it hasn't been implemented, yet.

Tics and other stuff for 3D plots are considerably less advanced in
their configurability than their 2D counterparts. One of the missing
things is second axis support. No x2, no y2, and no z2 axes in splots,
that means.

There's a more convenient way for the axis itself: use 'set border
4095' or a subset of bits to have gnuplot draw additional edges of the
box surrounding a 3D plot area. The default only gives a rightside
vertical axis from the baseplane up to the z value where the hightest
datapoint meets that corner of x-y space.
