PGPLOT Module: PGSFS -- set fill-area style


SUBROUTINE PGSFS (FS)
INTEGER FS

Set the Fill-Area Style attribute for subsequent area-fill by
PGPOLY, PGRECT, or PGCIRC. Four different styles are available:
solid (fill polygon with solid color of the current color-index),
outline (draw outline of polygon only, using current line attributes),
hatched (shade interior of polygon with parallel lines, using
current line attributes), or cross-hatched. The orientation and
spacing of hatch lines can be specified with routine PGSHS (set
hatch style).


Arguments
FS (input) : the fill-area style to be used for subsequent
plotting:
FS = 1 => solid (default)
FS = 2 => outline
FS = 3 => hatched
FS = 4 => cross-hatched
Other values give an error message and are
treated as 2.
