The dial gauge is intended to show real-time data, if you have a SharePoint list which gets updated often, dial gauge is a good choice to show real-time data.
A few points about the dial gauge:
- Intended to show real-time updates to SharePoint lists
- Can show the Minimum/Maximum/Average/Median/Sum/First/Last/Row Count/Unique values of a SharePoint list
- Users can determine the visual range of the gauge (the min and max value on the gauge). Please note the final rendered range takes both user range and data range into account. For example, if the users entered visual range between 0 and 100, however the data ranges between 30 and 200, the final rendered range will be 0 and 200
- Color bands can be added
Here is an example (see below example live):
