If you have a data point that is messing up the desired view range of your gauge, you can set the min and/or max value of the gauge by doing the following:
1. Right-click on the desired tile (or long press if you are using a touchscreen device).
2. If the Type is selected as "gauge", there will be a Minimum Value and Maximum Value field at the bottom of the tile configuration settings that pop-up. Type in the desired maximum and/or minimum value.
3. Click the close button to save your changes.
If you leave either the Minimum or Maximum Value field blank, it will default to the max/min value in the entire data set for that signal (data stream).
