[Question] Graphing with a List

[Freire]

I want to make a graph like this:

Code:

FOR k FROM 1 TO 500 STEP 2 DO
y:=k*0.15;
x1:=30+f1(k)*0.15;
x2:=30+f2(k)*0.15;
ARC_P(G0,x1,220-y,0.1,RGB(0,0,255));
ARC_P(G0,x2,220-y,0.1,RGB(255,0,0)); END;

But it takes a long time to evaluate the functions(the functions do lots of tasks), taking like 30 seconds to finish the plot.
To solve this I tried to make lists with values, then to copy to my program,
But I don`t know how to copy the values in an easy way instead of formatting myself.
Does someone has an easy solution for this?

Code:

L1:=MAKELIST(30+f1(k)*0.15,k,1,500,2);
L2:=MAKELIST(30+f2(k)*0.15,k,1,500,2);
L3:=MAKELIST(k*0.15,k,1,500,2);
