Gauge Visualization Widget

Hi Developers,

I wanna have multiple gauges in web application to show the status of some industrial packages. I use the VaadinVisualization but I don’t know how to change the value without refreshing the page. The Google Chart Tools do that very nicely without refreshing the page by showing the motion of changing the indicator
https://developers.google.com/chart/interactive/docs/gallery/gauge
. It’s so nice.

When I use the Google Chart Tools I faced with the error :
com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.google is undefined

How can I do that?

I wanna set new value of gauge in every 1 minute without refreshing the page.
