- Description:
This attribute specifies a label to be attached to each axis of
a Frame when it is represented (e.g.) in graphical output.
If a Label value has not been set for a Frame axis, then a
suitable default is supplied.
- Type:
- String.
- Class Applicability:
-
Frame
-
The default supplied by the Frame class is the string "Axis
<n>", where <n> is 1, 2, etc. for each successive axis.
-
SkyFrame
-
The SkyFrame class re-defines the default Label value
(e.g. to "Right ascension" or "Galactic latitude") as
appropriate for the particular celestial coordinate system
being represented.
-
FrameSet
-
The Label attribute of a FrameSet axis is the same as that of
its current Frame (as specified by the Current attribute).
- Notes:
-
Axis labels are intended purely for interpretation by human
readers and not by software.
-
When specifying this attribute by name, it should be
subscripted with the number of the Frame axis to which it
applies.
