A pie chart describes the proportions of different types. It measures the proportion of each type by the slice size. It is suitable for proportion statistics scenarios, for example, analyzing the proportions of different error codes.

Chart Style
Pie Chart Type: Control the pie chart style. A solid chart is a pie chart, and a hollow chart is a donut chart.
Metric Aggregation: This is an advanced feature that allows you to select a method for aggregating the values of the same metric before plotting. For example, if a range of values containing results from multiple time points is returned for a metric, the system aggregates the values from all those time points before plotting. By default, no aggregation is performed. You can set a limit on the maximum number of metrics to be displayed. Any metrics beyond this limit are hidden.
Sort By: Control the slice sorting order, which can be ascending and descending. Sorting is disabled by default.
Top Items to Show: Merge slices other than top N slices into the "Others" slice. If there are too many slices, you can use this feature to focus on top N slices.
Tag: Display pie chart labels. You can set name, value, and/or percentage as tags.
