One way to simplify your code is to do:
data:=NULL;
while ... do
x:=evalf(...):
y:=evalf(...):
data:= data, [x,y];
od:
plot([data]);

Inside a loop you need to use print(plot(...)) in order to see all the plot
output reliably. This is because plot just returns a plot data structure
and does not actually do any plotting; the print forces the value returned
by plot to be displayed.

Yes, it is. The one pitfall if you are using plot in
a procedure or nested loops is that plot doesn't automatically
put its output on the screen; as in most other commands, the output
will not normally be visible if the command is inside a nested loop
or inside a procedure (and not producing the return value of the
procedure). To make sure that you do see the output, you can use
print(plot(...)).

Hi,
Just add a "print(plot([data])" between the "do" and the "od".
