hello, please i need your help please help me

I want the window remains open and the graph continues to emerge each time the coordinates is calculated the first step: the window opens and there's just ordinate and abscissa. the second stage: once the factorial function computes factorial (k = 2) then the window displays the graph (k = 1, fact (k = 1) = 1) (k = 2, fact (k = 2) = 2) (the line) (as it did the update to the window and it displays the line and the window remains open after the factorial function computes factorial (k = 3) while the window displays the graph (k = 2, fact (k = 2) = 2) (k = 3, fact (k = 3) = 6) (line) ex ..

/*I do not want the loop

you then you calculate the poster I want to draw each time for giving and its factorial k

I give you another example as the task manager----->Performance

you see the pattern I want my program to do exactly

In fact I want the same result (a visual standpoint), but I used what has already been drawn before, just by adding new lines ...

please i need your help ,please
