# Analytics statements supported in the Chart component

This topic describes the three types of Analytics statements that can be expressed in the Chart component.

The Analytics use cases are:

- Zero GROUP BY statements, with one or more metrics One or more metrics summarized by a single unspecified grouping (the name of which defaults to "Total").
- One GROUP BY statement, with one or more metrics One or more metrics summarized by a single specified categorization.
- Two GROUP BY statement, with one metric One metric summarized by a specified categorization, with a second GROUP BY statement specified as the cross tab. (Cross tabs are grouped aggregations such as cross-tabulated totals over one or more dimensions.)

Various expressions of these types are shown in the chart style examples later in this section.
