NormUnit(axis) - Normalised Axis physical units

Description:
The value of this read-only attribute is derived from the current value of the Unit attribute. It will represent an equivalent system of units to the Unit attribute, but will potentially be simplified. For instance, if Unit is set to "s$*$(m/s)", the NormUnit value will be "m". If no simplification can be performed, the value of the NormUnit attribute will equal that of the Unit attribute.
Type:
String, read-only.
Class Applicability:
Frame
All Frames have this attribute.
Notes:
  • When specifying this attribute by name, it should be subscripted with the number of the Frame axis to which it applies.
