How can I separate these graphs?

Hi Everyone, I wrote this script and it works, also its plots. Now I would like to separate these graphs (they are overlapping). How can I do it? I don't think subplot is my answer. Thank you so much again!

clc
clear all

L=20; %m
A=25; %m^2
E=30000000; %KPa
m=1275000/L;  %Kg/m
I=52.08;    %m^4

betaL=[1.8751 4.6941 7.8548 10.996 14.1372];
beta=betaL./L; %normalize

omega=sqrt(beta.^4*E*I/m);

x=[0:0.1:20];  

C1=0.005;      %costant

for j=1:5

      for i=1:length(x)

            %displacements
            Fi(i,j)=C1*(cosh(beta(j)*x(i))-cos(beta(j)*x(i))-(cosh(betaL(j))+cos(betaL(j)))/(sinh(betaL(j))+sin(betaL(j)))*(sinh(beta(j)*x(i))-sin(beta(j)*x(i))));

      end
  end

Z=zeros(length(x),1);

%plot
figure(1)
plot(Fi,x');
hold on;
plot(Z,x','k');
title('Displacement');
xlabel('u [m]');
ylabel('L [m]');

Answer 1

[Roger Stafford]

You have given 'plot' a 201 x 5 matrix, F1, to be plotted against a 201 x 1 column vector, x'. Under those circumstances 'plot' is supposed to give you five different 2D plots on the same graph, and they must necessarily overlap. If you want them to appear on separate graphs, then give each column, F1(:,j), to be plotted against x' for separate graphs, one at a time for each of the five values of j.

Use the subplot function:

%plot
figure(1)
subplot(2,1,1)
plot(Fi,x');
title('Displacement');
xlabel('u [m]');
ylabel('L [m]');

subplot(2,1,2)
plot(Z,x','k');
title('Displacement');
xlabel('u [m]');
ylabel('L [m]');
