Plot multiple lines in Matlab with animation

Hi all,

I am trying to plot a line, and then another line

I already wrote the code, but the figure plotted not as I want (I attached what i want)

Any help please :

clc;
close all;
clear all;
nodal_coo=[0 0;1 0;2 0;3 0];
element_coon=[1 2;2 3;3 4];
disp=[0,0,.24,0,-0.2076,.1245,0,-2076,-.1245,0,0,-2491]; 
NE=3;
for i=1:NE

    ncon(1)=element_coon(i,1)
    ncon(2)=element_coon(i,2)
    eldof=[3*element_coon(i,1)-2;3*element_coon(i,1)-1;3*element_coon(i,1);3*element_coon(i,1)-2;3*element_coon(i,1)-1;...
           3*element_coon(i,1)] 
       del(:,i)=disp(eldof);   % DISPLACEMENTS OBTAINED in arry form 
end 
f=figure;
hold on; 
for i=1:NE
    line(nodal_coo(element_coon(i,:),1),nodal_coo(element_coon(i,:),2),'linewidth',5,'color','b');
    line(nodal_coo(element_coon(i,:),1)+del([1,4],i),nodal_coo(element_coon(i,:),2)+del([2,5],i),'linewidth',10,'color','r');
end

could you add more explanation? what are the coordinate in your attached picture?

Hi,

Thanks for your reply,

The coordinates is in the code:

nodal_coo;

which means coordinates in x y and element_coon; means the nodal connectivity
