Like a Comparative Fill gauge, a Comparative gauge shows the degree of change between a previous value and a current value. However, Comparative gauges lack graphical elements and consist solely of a percentage value. They do not require minimum, maximum, or target values. The degree of change may be shown as a percentage or as a straight value. Alternatively, you may choose to show only the current value. You can change this setting in the chart properties. Learn more about [other gauges](/s/article/360042924334) in Domo. *** ## Power a Comparative Gauge A Comparative gauge requires only two columns or rows of data from your DataSet. One of these contains the current value for the gauge, and the other contains the previous value. If multiple rows are present in your DataSet, only the *first* row is used. No aggregations occur. In Analyzer, you choose the columns containing the data for your Comparative gauge. For more information about choosing data columns, see [Applying DataSet Columns to Your Chart](/s/article/360043428713 "Applying DataSet Columns to Your Chart"). The following graphic shows you how the data from the previous and current value columns in a typical column-based spreadsheet is converted into a comparative gauge:

## Unique Properties — Comparative Gauge You can customize the appearance of a comparative gauge by editing its chart properties. This table describes the properties unique to Comparative gauges. For information about other available properties, see [Properties for Gauges](/s/article/360042925354 "Chart Properties").

Property	Description	Example
General > Value displayed	Determines whether the displayed value is the percent of change between the previous and current value (default), the actual change in value, or the current value. For example, the previous value in your DataSet was 30 and the current value was 55. If you select Percentage Change the gauge displays "83.3%," which is the percentage of change between 30 and 55. Make sure that the General > Value Format property is set to Percentage . See Properties for Gauges to learn about the General > Value format property. If you select Value Change , the gauge displays "25," which is the actual difference between the two values. If you select Value Change or Current Value for this property, make sure that the General > Value Format property is set to Number ; otherwise, your gauge value will have an unnecessary percent symbol. See Properties for Gauges to learn about the General > Value format property.	—
General > Show label	When enabled, a label displays above the value.
General > Override color	Allows you to select a color for the gauge. If you choose a color for this property, it overrides any color selections for positive or negative values.

Property

Description

Example

General > Value displayed

Determines whether the displayed value is the percent of change between the previous and current value (default), the actual change in value, or the current value.

For example, the previous value in your DataSet was 30 and the current value was 55.

If you select Percentage Change the gauge displays "83.3%," which is the percentage of change between 30 and 55. Make sure that the General > Value Format property is set to Percentage . See Properties for Gauges to learn about the General > Value format property.
If you select Value Change , the gauge displays "25," which is the actual difference between the two values.
If you select Value Change or Current Value for this property, make sure that the General > Value Format property is set to Number ; otherwise, your gauge value will have an unnecessary percent symbol. See Properties for Gauges to learn about the General > Value format property.
