You will need a bit of AJAX to achieve your objective.
Define a JS function like
<script>
function update_item(pNow) {
  setTimeout("update_item(true)",15000);    // 15000 is time in ms - should match your charts refresh time
  if (pNow){
     var get = new htmldb_Get($x('P16_X'),$x('pFlowId').value,'APPLICATION_PROCESS=UPDATE_INFO',0);     // P16_X is the page-item that needs refreshing ,UPDATE_INFO is an Application Process
gReturn = get.get();
</script>In the Chart Region's ' Region Footer' add
<script>
addLoadEvent(update_item(false));
</script>Define an On-Demand 'Application Process' named 'UPDATE_INFO'. For the process text do something like
declare
newvalues varchar(200);
begin
   newvalues := 'Whatever my newvales for query time etc are ....';
   htp.prn(newvalues);
end;And that should be it
