Dear Felows,
Do you know is there any way that I can name the marker by myself instead using the the default ones? For example, if I am plotting vectors of 65 dimentions, how can I name each point in the plot as the number from 1 to 65? My current code is
if true
% h=scatter(pf(:,1),pf(:,2),'.') % pf is 65*2 matrix containning numbers
saveas(h,num2str(i), 'jpg')
end
Currently the markers are all '.' so I am unable to distingush them. I would like them to be from number 1 to 65 according to the rows of the matrix. For example, if the 3rd rows of pf is (25,30), I want the marker is number 3 for this point.
Thanks, Xueqi
