This chart is mostly used in dashboards, to show the progress of one or more indicators against their established targets. The chart plots the progress as a percentage, in the form of a bar chart or a donut chart.
You can add more information to the chart, such as the change percentage and the difference against the previous period.
The difference between a progress bar chart and a donut chart is in the space they take. Choosing one or the other is mostly an aesthetic decision.
Metric charts are a specialized subset of bar and donut charts. If you are not building a dashboard or if you want to compare more than 1 category, a bar chart or a donut chart may be more appropriate.
If you want to show the actual value of an indicator, use the KPI value component.
