Specifies which edges of the 3D box should be annotated
The attribute value should consist of three character, each of which must be either "
U"
or "
L"
. The
first character in the string specifies the position of the corner on the first graphics axis. If the
character is "
U"
then the corner is at the upper bound on the first graphics axis. If it is "
L"
, then the corner is at the lower bound on the first axis. Likewise, the second and third
characters in the string specify the location of the corner on the second and third graphics
axes.
For instance, corner "
LLL"
is the corner that is at the lower bound on all three graphics axes,
and corner "
ULU"
is at the upper bound on axes 1 and 3 but at the lower bound on axis
2.
The default value is "
LLL"
.
