SYNOPSIS

C SYNTAX

void marker_orientation(fildes,x,y);
int fildes;
float x,y;

FORTRAN77 SYNTAX

        integer*4 fildes
        real x,y

PASCAL SYNTAX

DESCRIPTION

INPUT PARAMETERS

fildes
is an integer file descriptor returned by gopen when an I/O path to a graphics device is opened. 
x,y
are components of a vector relative to (0.0,0.0) that determines the orientation of subsequent marker symbols.

DISCUSSION

The marker orientation vector determines the slant of marker symbols and is not a rotation.  That is, the orientation vector determines the movement away from the vertical of subsequent marker symbols. 

DEFAULTS

x=0.0, y=1.0.
