A request already under way that this panel shows and reports as its own,
for a host whose history load rebuilds the chart and so closes the panel
that started it. A closed panel reports nothing.
Methods
Optionalcancel
cancel():void
Abandon the panel's request. Called when the panel closes while that
request is still loading (dismissed, or closed by an interval or timezone
change), so the view cannot jump after the user has moved on; not called
when the panel closed because its chart was destroyed.
