Intro

Gauges are simple charts that indicate progress towards meeting a target. A Radial gauge is similar in appearance to a speedometer in a car, with a "needle" that moves to indicate the proximity of the current value to the goal. Radial gauges can include up to six ranges. Other gauge types in Domo include Single Value gauges, Filled gauges, Progress Bar gauges, Face gauges, and Comparative Fill gauges.

Powering Radial gauges

A Radial gauge requires only two columns or rows of data from your DataSet—one contains categories, and the other contains the values. This creates a "bare-bones" Radial gauge without ranges. You can specify up to six different ranges in a Radial gauge in Chart Properties. For more information, see Setting Properties for Gauges and Chart Properties. For information about value, category, and series data, see Understanding Chart Data.

The maximum value of a Radial gauge is automatically determined based on the current value. For example, if your current value was 80, the maximum value would be set to 100. If the current value was 155, the maximum value would be set to 200. However, you can set custom minimum and maximum values by specifying ranges. The minimum value of your first range is the minimum value of the gauge, and the maximum value of your last range is the maximum value of the gauge.

By default, all of the values in your values column are summed to produce the final value for the chart, even when you select No Aggregation in the value aggregation menu. This is because the General > Value chart property for this chart type is set to Sum by default. This property performs a second aggregation on the chart value in addition to the one selected in the value aggregation menu.

Note: Because having two aggregations in a chart is usually undesirable, select No Aggregation in the value aggregation menu, then select your desired aggregation in the General > Value menu in Chart Properties.

For more information about aggregating data, see Aggregating your data.

In the Analyzer, you choose the columns containing the data for your Radial gauge. For more information about choosing data columns, see Applying DataSet Columns to Your Chart.

For more information about formatting charts in the Analyzer, see KPI Card Building Part 2: The Analyzer.

The following graphic shows you how the data from the category and value columns in a typical column-based spreadsheet is converted into a Radial gauge:

Customizing Radial gauges

You can customize the appearance of a Radial gauge by editing its Chart Properties. For information about all chart properties, see Chart Properties. For more information about gauge properties, see Setting Properties for Gauges.

Property

Description

General > Value

Determines how the values in your values column are to be aggregated. Options include the usual aggregations such as Sum, Average, etc., as well as First Row and Last Row, which take the value in the first or last row as the gauge value. The default option is Sum. The aggregation you select here is added to the aggregation you select in the value aggregation menu (so, for example, if you selected Average in the value aggregation menu and Sum in Chart Properties, your gauge value would be the summed averages for each category).

Because having two aggregations in a chart is usually undesirable, select No Aggregation in the value aggregation menu, then select your desired aggregation in the General > Value menu in Chart Properties.

Range 1-6 > Minimum Value

Lets you specify the minimum value for the selected range.

Range 1-6 > Maximum Value

Lets you specify the maximum value for the selected range.

Range 1-6 > Color

Lets you select a color for the selected range.
