Bug or feature? set xyplane AT ...

[Philipp K. J. <ja...@ie...>]

When playing with set xyplane, I discovered
the following behaviour:

When using set xyplane without the AT keyword,
the vertical lines of the surrounding box (borders)
are extended to the the location of the base
plane (or shortened, as the case may be).

When using set xyplane with the AT keyword,
the vertical lines are unaffected, potentially
leading to strange results.

Example:

All good:
unset xyplane
set border 8191
set xyplane 1
splot [-3:3][-3:3][0:1] exp(-x**2-y**2)

Funny:
unset xyplane
set border 8191
set xyplane at -1
splot [-3:3][-3:3][0:1] exp(-x**2-y**2)

I am not sure whether this is intended behavior
or not. Certainly not critical, but I wanted to point
it out.

(Version info below)

Best,

		Ph.
