I am supposed to plot 3 curves on the same figure, The first plot is ok( the red one ), but the other 2 I am getting 2 separated curves for each plot..is there any idea to help me solve this problem?
Thanks in advance.

It seems the x-coordinates are not arranged in an increasing order.

How are you calculating the positions? Are you possibly using roots() or solve() or vpasolve() ?

Insead of using
plot(x,y)
try
[sorted_x,I] = sort(x);
sorted_y = y(I);
plot(sorted_x,sorted_y)
for the green and blue curves.
