plpath — Draw a line between two points, accounting for coordinate transforms


plpath(n, x1, y1, x2, y2)


Joins the point (x1, y1)  to (x2, y2) .  If a global coordinate transform is defined then the line is broken in to n segments to approximate the path.  If no transform is defined then this simply acts like a call to pljoin(3plplot).

Redacted form: plpath(n,x1,y1,x2,y2)

This function is used in example 22.


n (PLINT, input)

number of points to use to approximate the path.

x1 (PLFLT, input)

x coordinate of first point.

y1 (PLFLT, input)

y coordinate of first point.

x2 (PLFLT, input)

x coordinate of second point.

y2 (PLFLT, input)

y coordinate of second point.
