Polygonal (Broken) Line
To plot a polygon line defined by Cartesian coordinates of its vertices
select Broken Line in the Choose Curve Type window, press OK and enter linee
definition in the following format:
(x1,y1)±
(x2,y2)±
(x3,y3) ±
...
where each pair of numbers specivies Cartesian coordinates of a vertex. Put '+'
between vertices to connect them with a line segment, or '-' if you want to omit
the segment.
Examples:
(0,0)+(0,1)+(1,0)+(0,0) defines a triangle with given vertices
(0,0)+(0,1)-(0,1)+(1,1) defines two parallel segments
