CALL POINT (PX,PY)

#include <ncarg/ncargC.h>

void c_point (float px, float py)

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.

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

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.

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

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