Another request, i think whit ajax/jquery
whenn moving inside graphing
u will notice updates off graph.php whit time from and to
now the trick whenn the page refresh itself… the from / to is still what is was original.
so your graph will go back to that dates
or disable the refresh page when zooming into graph.
or set the from / to dynamicly whit ajax calls? en honor the from/to times while refreshing.
