When I use line in Sage. it will draw a line for me, with given points, and connect the point with straight line. but now I want to draw more than one line in a coordinate(to compare with each other). I try my best to do this ,but unfortunately, I failed. this can draw a line in the coordinate ,but now i want more than one. how can i do it? |
