DrawPolyline(Xs, Ys)The function draws a polyline using arrays of x and y coordinates. By default the color of polyline is white and width is 1 pixel. Example:
Xs[1] = 100 Xs[2] = 150 Xs[3] = 200 Xs[4] = 250 Xs[5] = 300 Ys[1] = 100 Ys[2] = 200 Ys[3] = 100 Ys[4] = 200 Ys[5] = 100 DrawPolyline (Xs, Ys)This is how result would look like (red coordinates are just for reference):
