SYNOPSISCALL POINT (PX,PY)
C-BINDING SYNOPSIS#include <ncarg/ncargC.h>
void c_point (float px, float py)
- (an input expression of type REAL) defines the X user coordinate where the dot is to be drawn.
- (an input expression of type REAL) defines the Y user coordinate where the dot is to be drawn.
C-BINDING DESCRIPTIONThe C-binding argument descriptions are the same as the FORTRAN argument descriptions.
USAGEIf 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.
EXAMPLESUse the ncargex command to see the following relevant examples: tareas.
ACCESSTo use POINT or c_point, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
