CURVE - draws the curve defined by a specified series of points in the user coordinate system. The "pen" (for subsequent calls to FRSTPT, VECTOR, PLOTIF, and PLOTIT) is left at the location of the last point in the curve.
CALL CURVE (PX,PY,NP)
void c_curve (float *px, float *py, int np)
The C-binding argument descriptions are the same as the FORTRAN argument descriptions.
If the routine SET was not called, or if it was called with a linear mapping in both the X and Y coordinates, then the GKS routine GPL is called to output a polyline of length NP points. If the mapping in either axis is logarithmic, the input coordinates are transformed and drawn ten points at a time. (The last segment may be less than ten points.)
Polyline type, line width, and color can also be set by calling the GKS routines GSLN, GSLWSC, GSCR, and GSPLCI, before calling CURVE.
Use the ncargex command to see the following relevant examples: sfex01, sfex02, and tsoftf.
To use CURVE or c_curve, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
