plshade:  Shade individual region on the basis of value 

DESCRIPTION:

    Shade individual region on the basis of value.  Use plshades if you
    want to shade a number of regions using continuous colors. plshade is
    identical to plshade1 except for the type of the first parameter. See
    plshade1 for further discussion.
