Name: PGARRO Purpose: draw an arrow Category: GRAPHICS File: pgplot.src Author: T.J. Pearson Use: see description below. Description: SUBROUTINE PGARRO (X1, Y1, X2, Y2) REAL X1, Y1, X2, Y2 Draw an arrow from the point with world-coordinates (X1,Y1) to (X2,Y2). The size of the arrowhead at (X2,Y2) is determined by the current character size set by routine PGSCH. The default size is 1/40th of the smaller of the width or height of the view surface. The appearance of the arrowhead (shape and solid or open) is controlled by routine PGSAH. Arguments: X1, Y1 (input) : world coordinates of the tail of the arrow. X2, Y2 (input) : world coordinates of the head of the arrow. Updates: Oct 16, 1998: JPT automatically extracted from source.
