    Tkinter Canvas


    Okay I have a program which makes a graph in a Canvas and everything works except the Ploting of points...

    Code:
    from Tkinter import *
    import math,Pmw
    
    class Grid:
        def __init__(self):
            self.root = Tk()
            self.Grid()
            self.root.mainloop()
    
        def Grid(self):
            self.Can = Canvas(self.root, width = 800, height = 700)
    
            self.Can.create_line(0,50,800,50)
            self.Can.create_line(0,100,800,100)
            self.Can.create_line(0,150,800,150)         # X cor ______________
            self.Can.create_line(0,200,800,200)
            self.Can.create_line(0,250,800,250)                
            self.Can.create_line(0,300,800,300)           # X middle
            self.Can.create_line(0,349,800,349,fill="blue")
            self.Can.create_line(0,350,800,350,fill="blue")
            self.Can.create_line(0,351,800,351,fill="blue")
            self.Can.create_line(0,400,800,400)
            self.Can.create_line(0,450,800,450)
            self.Can.create_line(0,500,800,500)
            self.Can.create_line(0,550,800,550)
            self.Can.create_line(0,600,800,600)

            self.Can.create_line(100,0,100,700)
            self.Can.create_line(150,0,150,700)
            self.Can.create_line(200,0,200,700)            # y cor |||||||||||||
            self.Can.create_line(250,0,250,700)

            self.Can.pack()
    
        def Plot(self,x,y):
            cx1 = x+5
            cy1 = y+5
            cx2 = x-5
            cy2 = y-5
    
            lx1 = x+2
            ly1 = y+2
            lx2 = x-2
            ly2 = y-2
    
            self.Can.create_line(lx1,ly1,lx2,ly2,fill="red")
            self.Can.create_oval(cx1,cy1,cx2,cy2,outline="red")
            
    if __name__ == "__main__":
        g = Grid()
        g.Plot(100,100)
    The Ploting does not work but I don't know why?
