Bottom(axis) - Lowest axis value to display   

Description:
This attribute gives the lowest axis value to be displayed (for instance, by the AST_GRID method).

Type:
Floating point.

Class Applicability:
Frame
The default supplied by the Frame class is to display all axis values, without any limit.
SkyFrame
The SkyFrame class re-defines the default Bottom value to -90 degrees for latitude axes, and 0 degrees for co-latitude axes. The default for longitude axes is to display all axis values.

Notes:
  • When specifying this attribute by name, it should be subscripted with the number of the Frame axis to which it applies.
