Dear Mahdi, Thank you so much. I found the solution by your answer :). a = pointid ; b = num2str(a); c = cellstr(b); dx = 0.1; dy = 0.1; % displacement so the text does not overlay the data points text(x1+dx, y1+dy, c);

hold on
% Get the values from the matrix
point_id=Matrix1(:,1);
x=Matrix1(:,2);
y=Matrix1(:,3);
% Set the text to show up
for i=1:length(x)
text(x(i),y(i), point_id)
end
Note that you can also do this without redefining the values again. I just did it for clarity.
