How to adjust the accuracy in graphs ?

Hi,I plot a graph ,I Wan to display on the graph on each (X,Y) couple, the real value of X ,I mean for exemple my data is like X=388.234565 ,

in the graph matlab just display the first number after the comma 388.2 which decrease the accuracy of my analysis .is it possible to dissplay the real values of X with several numbers after comma.

h = plot(rand(10,1));
h.DataTipTemplate.DataTipRows(1).Format = '%.6f';       % first line of datatip
datatip (h,'DataIndex',3);      % datatip at 3rd point
