NAME

6       POINT - draws a point at a specified position in the user coordinate
7       system.
8

SYNOPSIS

10       CALL POINT (PX,PY)
11

C-BINDING SYNOPSIS

13       #include <ncarg/ncargC.h>
14
15       void c_point (float px, float py)
16

DESCRIPTION

18       PX          (an input expression of type REAL) defines the X user
19                   coordinate where the dot is to be drawn.
20
21       PY          (an input expression of type REAL) defines the Y user
22                   coordinate where the dot is to be drawn.
23

C-BINDING DESCRIPTION

25       The C-binding argument descriptions are the same as the FORTRAN
26       argument descriptions.
27

USAGE

29       If one desires a filled dot of arbitrary size see the routine NGDOTS.
30
31       The GKS routine GPM can also be used to draw a dot in world
32       coordinates; however, NCAR Graphics user coordinates allow for mirror
33       imaging of axes and logarithmic axes which GKS does not.  See the SCD
34       User Doc "NCAR Graphics Fundamentals, UNIX Version" for a description
35       of these coordinate systems.

EXAMPLES

ACCESS

41       To use POINT or c_point, load the NCAR Graphics libraries ncarg,
42       ncarg_gks, and ncarg_c, preferably in that order.
