In 2013b I have used a function that calculates the difference between two data cursors. So when I move one cursor it will update dy and dx on both cursors and of course display the correct position. In 2013b it was quite simple to update the datacursor with your string using something like this;

cursorMode=datacursormode(gcf);
cursors=cursorMode.DataCursors;
set(cursors(x),'String',yourstr)

You could even get the active cursor by

currentCursor=cursorMode.CurrentDataCursor;

However, now this doesnt work and I cant find any solution to get around the issue. When following the example at http://se.mathworks.com/help/matlab/ref/datacursormode.html only the active cursor is updates.
