First, add a tooltip column definition to your header:
$data[] = Array('clock', 'Value', Array('type' => 'string', 'role' =>
'tooltip'));
then you can add the tooltip data to your array in the loop:
$data[] = Array($date, $history->value, $phist[$i]->value);
If that doesn't work, post the JSON output by your php.
