I have the scatter diagram and I want the coordinates of each point

What I want is, if I have the scatter diagram, how can I take the coordinates of each and every point in a matrix or in a vector?

Can you be more specific when you say you "have the scatter diagram"? Do you only have an image (like a PNG file), or do you have a MATLAB-generated figure window open, etc.

sorry for all that mesh. Well the scatter I have it from the below code

axis ij
hold on
while any(A(:) > 0)
  [r,c] = find(A>0);
  offx = randn;
  offy = randn;
  scatter(c+offx,r+offy,'.', 'b')
  A = A-1;
end

but I can't understand how to find the x,y coordinates of each point

Could you add some sample A data? It seems to me the

   scatter(c+offx,r+offy,'.', 'b')

line contains the X and Y data. So X_new and Y_new becomes:

New_X=c+offx;
New_Y=r+offy;

How did you generate the picture? If it was via MATLAB, then why don't you know the coordinates already?

Maybe this will help: http://www.mathworks.com/matlabcentral/fileexchange/36904-matlab-script-for-digitizing-a-published-graph

Or else, call ginput() or impoints(). You will also have to click on the start and stop of the x and y axes so that you can locate the origin and a spatial calibration factor.

Regarding your clarification above...

The "x" values are c+offx,

and the "y" values are r+offy.

Ops!!! you have right , thanks
