By default, the Gauge dashboard item automatically determines the range of the gauge scales based on the values they display.
You can override this behavior and specify the maximum and minimum values on the scale.
To do this, invoke the Gauge Options window using the Options button displayed in the data item container in the Gauges section of the DATA ITEMS pane.
In the Gauge Options window, uncheck the Auto check box for the maximum or minimum value, and specify this value in the corresponding field.
