Intraday (1 minute) Data plugin update quotes but chart was not redrawed

I developed a plugin to use in house. It worked fine with Amibroker 5.6 but when I buy Amibroker 6.3 license, EOD is fine but failed to update realtime with Intraday (1 minute database type).
Data pushed to Amibroker in realtime but chart only update when I press F5 or choose new symbol or when there is a new bar. (please see the attach image)
When I choose Tick in View menu, chart will be redraw in realtime again.
Please help,
