Syntax:
set ticslevel <frac>
set xyplane <frac>
set xyplane at <zvalue>
show xyplane
The form set ticslevel
frac
places the xy plane below the range in Z, where
the distance from the xy plane to Zmin is given as a fraction of the total
range in z. The default value is 0.5. Negative values are permitted, but tic
labels on the three axes may overlap.
To place the xy-plane at a position 'pos' on the z-axis, ticslevel may be set equal to (pos - zmin) / (zmin - zmax). However, this position will change if the z range is changed.
The alternative form set xyplane at
zvalue
fixes the placement of the
xy plane at a specific Z value regardless of the current z range. Thus to
force the x, y, and z axes to meet at a common origin one would specify
set xyplane at 0.
