MATLAB: Changing the location of num2str

Question

Hi, I am using the following to illustrate the index of the (x,y) location inside a polygon. text(x(i),y(i),num2str(i) With the above code I get the numbers exactly on the (x,y) point. Does someone know how to change that location?

Answer 1

Add an offset to the x (and/or y) location:

 d = 0.01;  
 text(x(i)+d,y(i),num2str(i))

Remember that x and y are data units: you will need to pick a value of d that makes sense for your data.
