PGPLOT Module: PGCIRC -- draw a circle, using fill-area attributes


SUBROUTINE PGCIRC (XCENT, YCENT, RADIUS)
REAL XCENT, YCENT, RADIUS

Draw a circle. The action of this routine depends
on the setting of the Fill-Area Style attribute. If Fill-Area Style
is SOLID (the default), the interior of the circle is solid-filled
using the current Color Index. If Fill-Area Style is HOLLOW, the
outline of the circle is drawn using the current line attributes
(color index, line-style, and line-width).


Arguments
XCENT (input) : world x-coordinate of the center of the circle.
YCENT (input) : world y-coordinate of the center of the circle.
RADIUS (input) : radius of circle (world coordinates).
