The gauge chart is similar to Pie Chart and Donut Chart. It uses a needle to indicate the data point. It shows the maximum, the minimum, and the present value of the data being analyzed. A gauge chart is a type of data visualization often used to display a single data value with a quantitative context. With a shape that resembles a speedometer, this chart aims to track the progress of a KPI.
Use of Gauge Chart
It is important to consider that this type of visualization is mostly used to display one single value. The popular use of this chart is for target metrics. Using them in this context will help you understand the performance of a specific KPI based on a target you pre-defined.
