Drawing Lines or Curves

PLPLOT provides two functions for drawing line graphs. All lines are drawn in the currently selected color and line style. See page in Section and page in Section for information about changing these parameters.

plline draws a line or curve. The curve consists of n-1 line segments joining the n points in the input arrays. For single line segments, pljoin is used to join two points.

plline(n,x,y); n (int, input) the number of points. x, y (float *, input) pointers to arrays with coordinates of the n points.

pljoin(x1,y1,x2,y2); x1, y1 (float, input) coordinates of the first point. x2, y2 (float, input) coordinates of the second point.
