Using Gauge Charts
Use gauge charts to compare values for items in a measure. You can compare them to
another measure or to a custom amount. For example, gauge charts are useful when you
want to visualize data that represents liquid levels, such as ink usage.
To create a gauge chart, you need to use at least one measure in the Value field well. If you want to compare two measures, add the additional measure in the Target value field well. If you want to compare a single measure to a target value that is not in your dataset, you can use a calculated field that contains a fixed value.
