"specifies that a unit description should be included in the label for the second axis.
If the LabelUnits value of a Plot axis is non-zero, a unit description will be included in the descriptive label for that axis, otherwise it will be omitted. The default behaviour is to include a unit description unless the current Frame of the Plot is a SkyFrame representing equatorial, ecliptic, galactic or supergalactic coordinates, in which case it is omitted.
The text used for the unit description is obtained from the Plot
’ s Unit(axis) attribute.
If no axis is specified, (e.g.
" instead of
" ), then a
operation will affect the attribute value of all the Plot axes, while a
" operation will use
just the LabelUnits(1) value.
If the current Frame of the Plot is not a SkyFrame, but includes axes which were extracted from a SkyFrame, then the default behaviour is to include a unit description only for those axes which were not extracted from a SkyFrame.
