HELP
Mappings are implicit or explicit values that
express the independent variables for an
array.  For example, the mappings on a
Waveform are the times for each amplitude
value.  Waveform, Spectrum, and Coord data
types are mapped.  Arrays of other data types
can also be mapped by using Data ==> Access
Array ==> Set Mappings.

Mappings are either implicit (Waveform,
Spectrum, or mapped arrays created with Set
Mappings) or explicit (Coord).  Implicit
mappings are attached to the array and may be
viewed on the terminal or by using Line
Probe, but are not part of the array (they
are different than the array indices).
Explicit mappings are part of the array and
are displayed as the first n-1 fields in a
Coord value with n fields.

The sampling interval of linear mappings is
the maximum value minus the minimum value,
divided by the number of points.  There are
the same number of points as sampling
intervals; each point is at the beginning of
a sampling interval.

When mapped values (except Coord) are
displayed, the X axis displays the mapping
values.

To get information about an implicitly-mapped
array, use Data ==> Access Array ==> Get
Mappings.  Get Mappings gives you the type of
mapping (log or linear) and the minimum and
maximum mapping values.
