Is it normal that i can't plot in a function ?

Without a function:

plot(point([1, 1]))

With a function:

def toto():
    plot(point([1, 1]))

Thanks in advance !

All the code is in the pictures. :(

It is better to write the code instead of providing picture. If I want to try the code it is simpler for me to do a copy paste... that is not possible with pictures.

First of all in your code you can replace plot(point([1,1])) by point([1,1]).

And the answer is yes. All plot functions return a graphic objects that can be further manipulated. In your function you are creating a graphic but not using it at all. The following code shows what is a graphic

sage: G = point([1,1])
sage: type(G)
<class ''>
sage: G    # will show the graphics

If you want that your function shows the graphic you can do

def my_graphic():
    G = point([1,1])

If you want that your function returns a graphic you can do

def my_graphic():
    G = point([1,1])
    return G

Thanks ! If I call several times the function, how can I concatenate the graphics to show them in one graph ?

Just use addition

sage: point([1,1]) + point([3,2])
