NAME¶

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

SYNOPSIS¶

CALL POINT (PX,PY)

C-BINDING SYNOPSIS¶

#include <ncarg/ncargC.h>

void c_point (float px, float py)

DESCRIPTION¶

PX

(an input expression of type REAL) defines the X user coordinate where the dot is to be drawn.

PY

(an input expression of type REAL) defines the Y user coordinate where the dot is to be drawn.

C-BINDING DESCRIPTION¶

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

USAGE¶

If one desires a filled dot of arbitrary size see the routine NGDOTS.

The GKS routine GPM can also be used to draw a dot in world coordinates; however, NCAR Graphics user coordinates allow for mirror imaging of axes and logarithmic axes which GKS does not. See the SCD User Doc "NCAR Graphics Fundamentals, UNIX Version" for a description of these coordinate systems.

EXAMPLES¶

Use the ncargex command to see the following relevant examples: tareas.

ACCESS¶

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