Use plotyy
% Example
x=0:0.01:10
y1=sin(x)
y2=100*cos(x)
plotyy(x,y1,x,y2)

I just want the red lines to continue as the blue lines end.Don't want to change the y-axis. Thanks.

Can you post your data, or something that looks like your data

for i=n:n+11
fin1(i)=u+(si*sqrt(-log(2*3.14159*si*v(i)*v(i))));
fin2(i)=u-(si*sqrt(-log(2*3.14159*si*v(i)*v(i))));
end;
plot(f(1:n));
hold on
plot(fin1(n+1:n+11),'r');
plot(fin2(n+1:n+11),'r');
Here's the code.I want to concatenate 'f' with 'fin1' and 'fin2'.The red plot should start when the blue plot ends.

Look at this example
close
clear
n=10
f=cos(0.1*(1:n)).^2
for k=n+1:n+10
fin1(k-n)=sin(0.1*k)
fin2(k-n)=cos(0.2*k)
end
plot(1:n,f,'b');
hold on
plot(n+1:n+10,fin1,'r')
plot(n+1:n+10,fin2,'r')
hold off

You mean something along the lines of:
x1 = 1:50; x2 = 1:10; x3 = 1:10;
y1 = rand(1,50); y2 = rand(1,10); y3 = rand(1,10);
x = [x1 x2+x1(end) x3+x1(end)+x2(end)];
y = [y1 y2 y3];
plot(x,y)
