I have a data set which i want to plot such that items 1,4,7,... are in one graph, item 2,5,8,... are in another and item 3,6,9,... are in the third. i have used the following code for plotting all these in one graph.
for i=1:n
subplot(1,n,i)
plot([0;f(:,i)],(0:h:h*n)])
end
can this be modified to get the desired graph?

Hi Abdul
I certainly think so. I've define a data vector that's sinus of numbers from -10 to 10 in 111 steps - but use your own data in stead.
% Set n to be your desired increment (in this case 3 as in 4-1)
x = linspace(-10,10,111);
data = sin(x);
n = 3;
figure;
for ii = 1:n
subplot(1,n,ii)
plot(data(ii:n:end))
end

So what you desire is to plot [1;4;7] with [1;2;3] on the y-axis in the first plot, [2;5;8] with [1;2;3] on the y-axis in the 2nd plot etc.?
If that's the case, just modify the code to
% Set n to be your desired increment (in this case 3 as in 4-1)
x = linspace(-10,10,111);
data = sin(x);
n = 3;
y = 1:n:length(x);
figure;
for ii = 1:n
subplot(1,n,ii)
plot(data(ii:n:end),y)
end
