Dynamic dashboard time frame + generating min, max, average values

Dynamic dashboard time frame + generating min, max, average values

I'm wondering if it's possible (and if so, then how) to be able to easily change the time frame of data that you want a dashboard to show. The only way that I've seen to modify the timeframe is to do it individually for each widget (and you're still not able to greatly specify the timeframe you would like). In my situation, I have a dashboard displaying multiple data fields from a sensor and I'd like to easily change the time window and have all the widgets update (primarily the graphs and dynamic table).

I'd also like to be able to show the minimum, maximum, and average values for some data fields (also based on the timeframe selected).

Thank-you

EDIT: I can now see that for tables/graphs, when you add a time interval you are then able to select a specific data/time range for the data to be displayed, but this is still on a widget-to-widget basis instead of the dashboard as a whole.
