The CoordArrTable class provides a way to describe X/Y coordinate data to the HLU library.
Header file: ncarg/hlu/CoordArrTable.h Class name: coordArrTableClass Class pointer: NhlcoordArrTableClass Fortran class function: <Not referenceable> Superclass: DataItem Composite classes: <None>Note: This object is only available from "C". Fortran programmers should use the CoordArrays object.

The CoordArrTable object uses two "tables" to do this:
the ctXTable and the ctYTable. These "table" resources are actually
arrays of arrays. The main array points to something of
type **var where type is specified by the
ctXTableType and ctYTableType resources. The easiest way
to understand this is to think about the table as an array of vectors.
Therefore, the "type" for the ctXTable and ctYTable
NhlGenArray is NhlPointer, because each element of the NhlGenArray array is
actually a pointer to a vector. Each element of each vector is of type
ctXTableType, and ctYTableType respectively.
The ctXTableType and ctYTableType resources must be set
for their respecive "Table" resource.
The Min and Max resources are computed if they are not set explicitly. If the ctXTable or ctYTable resources are reset to new values, the Min and Max values are recomputed unless the Min and Max values have been explicitly set by the user. If these resources are ever set, the programmer/user is taking responsibility for updating them if they need to be updated.
