Add and configure a gauge gadget

A gauge gadget depicts the value of a certain attribute as a percentage of a target value. For example, a gauge might depict the unemployment rate for a layer of US counties with census information. The target value in this case would be 100:

When a single feature is depicted, that feature's value for the source attribute is considered when compared to the target. In cases where more than one feature is selected, an aggregate of the values of the source attribute across the features is compared against the target. This aggregate can be any one of the following:

• The average value across the features
• The sum total of the values of all the features
• The minimum of the values of all the features
• The maximum of the values of all the features

There are three styles of gauge gadgets:

Half-donut gauge

Horizontal bar gauge

Vertical bar gauge
