ncl_mpisci man page
MPISCI — Given the area identifier of one of the areas defined by whatever database was last read by one of the EZMAPB routines MPLNAM, MPLNDM, MPLNDR, and MPLNRI, this function returns a suggested color index for that area.
int c_mpisci (int iain)
is an input expression of type INTEGER, specifying the area identifier of a particular area of interest.
The C-binding argument description is the same as the FORTRAN argument description.
The statement "ISCI=MPISCI(IAIN)" retrieves in ISCI the suggested color index for the area with area identifier IAIN. For example, if IMAD is the area identifier of the little island in Lake Superior called "Lake Madeline", then MPISCI(IMAD) has the value 6. The suggested color indices are defined in such a way as to ensure that areas that touch each other have different color indices.
To get a suggested color index for the area, at a specified level, that contains the area with a specified area identifier, use MPISCI in combination with MPIOAR (which see). For example, MPISCI(MPIOAR(IMAD,4)) has the value 6, which is the color index for "Wisconsin" or any portion thereof, and MPISCI(MPIOAR(IMAD,2)) = 5, which is the color index for "North America".
Use the ncargex command to see the following relevant examples: mpex11, mpex12.
To use MPISCI or c_mpisci, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
