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?

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.

text() offers horizontal and vertical alignment options so that you can say whether the text is to begin at that coordinates or end there or be centered there.
