Is it possible to show point id in figure

When we imported the data in Matlab as matrix with (point id, x,y) data is include coordinates. How to show point id's in figure? is that possible? thanks

Do you mean that you want to label the points with the string "Point id"?

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);

Glad I was of help :) Please "accept" the answer so that other contributors don't look at the post.

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.
