Label(axis) - Axis label

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.

TimeFrame

The TimeFrame class re-defines the default Label value as appropriate for the particular time 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.
