#### Description:

This attribute controls the appearance of an annotated coordinate grid (drawn with the astGrid function) by determining which edges of the cube enclosing the 3D graphics space are used for displaying numerical and descriptive axis labels. The attribute value identifies one of the eight corners of the cube within which graphics are being drawn (i.e. the cube specified by the `"` graphbox`"` parameter when astPlot3D was called tp create the Plot3D). Axis labels and tick marks will be placed on the three cube edges that meet at the given corner.

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`"` .

Type:

  String.
