Application Scenario
A multi-level pie chart, also known as a sunburst chart, refers to a pie chart with multiple levels and an inclusion relationship between levels.
Multi-level pie charts are suitable for displaying complex tree-structured data with parent-child relationships, such as geographic area data, company hierarchies, and quarterly or monthly time levels.
The radians of different colors in the inner circle show the sales of each region respectively, while the light-colored slices in the outer circle represent the sales of different brands in that region, as shown in the following figure.

Chart Feature
1. Advantage
Intuitive display of hierarchical structure: Multi-level pie charts can clearly display the hierarchical structure of data, allowing users to see the relationship of subordination between different categories at a glance.
Space saving: Compared to traditional pie charts, multi-level pie charts can display more information in limited space, making the chart more compact.
2. Disadvantage
Complexity: When there are too many levels of data, multiple levels of pie charts can appear overly complex, making it difficult for users to quickly understand the information conveyed by the chart.
Difficult to compare: Comparisons between different levels in a multi-level pie chart may not be as intuitive as in a single-level pie chart, especially when the size of the inner levels is not significantly different from the outer levels.
Example
Data Preparation
1. Log in to FineBI, click My Analysis, select a folder, and click New Subject, as shown in the following figure.

Drag the dimension field Region from the left to-be-analyzed area into the color bar in the Graphic Property area, drag Sales into the Size bar, and drag Region and Brand Description into the Fine-grained bar. After these operations, a multi-level pie chart will be generated in the analysis area. The radians of different colors in the inner circle of the pie chart represent the sales amount in each region, while the light-colored slices in the outer circle of the pie chart represent the sales amount of different brands within the region in the inner circle, as shown in the following figure.
Label Setting
Click the Label settings button in the Graphic Property area, and check both Display Label and Display Current-Level Dimension. The chart will then display the corresponding dimension and label for the current hierarchy, as shown in the following figure.
