3D plot of multiple columns of 2D data

Hi,

I'm wondering if someone can point me in the right direction. I have 16columns of data which use a common x-axis, making a 355x17 array. I can use stem3 to plot one of the columns, when i use the data cursor on the plot i see that x=1,y=my common x-axis designator, z=my data value from the array, this is all fine. what I would like to know is how i can offset the x value for the x,y,z so I can see all 16 rows in one 3D space.

The 'common x=axis' is just the numbered measurement, 1-355, the data columns lay anywhere between 0-10.

figure
 x=noz %my common x-axis or measurement number 1-355
y1=VelMASTERarray(:,2) %a column from my master array
y2=VelMASTERarray(:,3)
y3=VelMASTERarray(:,4)
y4=VelMASTERarray(:,5)
 stem3(y1)
% hold on
%  stem3(z+10,y2)
% stem3(x+1,y2)

None of the commented out attempts worked.

Any ideas if it is possible?

Best regards

Steve

A = rand(355,17) ;
x = 1:size(A,1) ;
figure
hold on
for i = 1:size(A,2)
   % plot3(x,i*ones(size(x)),A(:,i))
     stem3(x,i*ones(size(x)),A(:,i))
end

Hi KSSV, I did not realise my colleague was logged in on my work PC so it was me who raised the question and I will ask him to accept this as it is perfect. I don't know what the

i*ones(size(x))

line means (just that it works). I will now try to label the rows of data.

Thank you KSSV
