A Gauge Chart in reporting is compatible with which type of variables?

A Gauge Chart is specifically designed to represent quantitative data, making it compatible with numeric variables. This type of chart effectively visualizes the performance or measurement of a particular value against a target or threshold. By using a scale, the gauge indicates where a particular numeric value falls, whether it's in a satisfactory range, above, or below a designated target.

In a Gauge Chart, the main focus is on the numeric representation, which allows decision-makers to quickly glean insights into performance metrics, such as sales figures, completion rates, or satisfaction scores. This makes it essential that the variables being represented in a Gauge Chart are numeric, as opposed to textual, date, or boolean variables, which do not convey measurable quantities directly suited for gauge visualization.
