# Question:how can i draw many points relating x axis in a same coordinate?

## Question:how can i draw many points relating x axis in a same coordinate?

i got many float data from 'for' sentence relating x,e.g.

for i to 4 do
x := 0.01*i;
if (i = 1) then
y := 0.2;
z := 0.05:
elif (i = 2) then
y := 0.3;
z := 0.5:
elif (i = 3) then
y := 0.5;
z := 1.05:
elif (i = 4) then
y := 1.2;
z := 2.05:
else
end if;
end do;

i got the values of y and z relating x four times in this loop,(x&y:[0.01,0.2],[0.02,0.3],[0.03,0.5],[0.04,1.2] and x&z:[0.01,0.05],[0.02,0.5],[0.03,1.05],[0.04,2.05]).
so,i want to draw the points by two lines relating x axis (x=0.01..0.04) in a same coordinate.

i knew how to draw a point in a coordinate,like this
==============================
with(plots):
point1:=plot([[x,y]],style=point,symbol=point,color=red);
display([point1],labels=[x,y],axes=boxed,scaling=constrained);
==============================
but ,how can i continuously draw the points by plot method,furthermore draw the points by two lines about y and z (of course by two colors).if u hv some gud idea,please tell me,thank u!
