MATLAB: The Data Tip Text Update Function

data tipnum2strupdate function

pos = get(event_obj,'Position');
x = pos(1); y = pos(2);
output_txt = {['Y: ',num2str(y,4)]};
is straight out of the documentation, but for the life of me i can not figure how to get the following to work:
output_txt{end+1} = {['X: ',num2str(x,4)]};
i have tried all sort of things to num2str(x,???) to no avail. any insight is appreciated.

I think it should be:
output_txt{end+1} = ['X: ',num2str(x,4)];
