i need to plot many plots in a loop function.

function data=coa08xxx_lines(n) 
load xydata 
for u=X(:,n)
for i=Y(:,n)
data= plot(u,i);
end
end
end

This code only plots the graph of n, but i want it to plot all the graps. for example if n=3, then i want the plot of 3, 2 and 1 to appear as subplots.

function data=coa08xxx_lines(n) 
load xydata
ii=ceil(n/3);
jj=ceil(n/ii);
for k=1:n
  subplot(ii,jj,k)
  plot(u(:,k),y(:,k));
end

This does not seem to give the required answer, it gives single empty graphs.

[Azzi Abdelmalek]

Try this

function data=coa08xxx_lines(n) 
data=load('xydata');
%If xydta contains x and y variables
y=data.y;
u=data.u;
ii=ceil(n/3);
jj=ceil(n/ii);
for k=1:n
  subplot(ii,jj,k)
  plot(u(:,k),y(:,k));
end

still doesnt work,

this is the closest i got:

function data=coa08xxx_lines2(n)
load xydata;
u=X(:,n);
i=Y(:,n);
while n>=1;
    n=n-1;
    data=plot(u,i);
end
end

i am sure that this is correct but its missing something?! it only plots n, but i wan n,n-1,n-2....

   function data=coa08xxx_lines(n) 
data=load('xydata');
%If xydta contains x and y variables
y=data.Y;
u=data.X;
ii=ceil(n/3);
jj=ceil(n/ii);
for k=1:n
    subplot(ii,jj,k)
    plot(u(:,k),y(:,k));
end

That works,thanks alot. but can you give me a brief explanation of how it works. The code also works only when n=<9 , i want it to ignore n if n>9 and just plot n=9.
