This chart shows relative proportions of different categories to the whole as circle slices (sectors). The circle represents the total of all categories and equals 100%. The size of each segment indicates the proportion of each category to the total amount.
Pie charts are a good choice for demonstrating proportions of a small number of segments.

Use one color for multiple small sectors belonging to a larger category
Dimension. You can specify only one field here. Your data will be grouped by this field.
Color
Dimension. You can specify only one field here. Your charts segments will be colored according to it.
Measures
Measure. You can specify only one field here.
Sorting
Measure or dimension from the Color section. Affects area sorting. The sorting direction is marked with an icon next to the field: for ascending or for descending. To change the sorting direction, click the icon.
Labels
Measure. Displays measure values on the chart. To add callouts with category names to the chart, drag the Measure Names dimension to this section. Markup functions are supported. For String type fields, you can configure using basic Markdown in DataLens On-premises syntax: click the icon before the field name and enable Markdown.
Segments. With too many segments, your chart will look cluttered, making it difficult to interpret the data. If there are more than 4-6 segments in one chart, consider combining the smallest of them into one segment, e.g., Other. You can do this by processing the data, e.g., by creating a calculated field in your dataset or chart.

To combine multiple segments by the ProductSubcategory field into a joined group:
Add a new field to the chart with the following formula:
CASE [ProductSubcategory]
WHEN "Beauty and health equipment" THEN "Beauty and health equipment"
WHEN "Kitchen" THEN "Kitchen"
WHEN "Kitchenware" THEN "Kitchenware"
ELSE "Other"
END
Drag the new field to the Color section.
Drag the Sales field to the Measures and Signatures sections.
The sales amount will be calculated separately for the Beauty and health equipment, Kitchen, and Kitchenware subcategories; for other subcategories, in the Other group.
Segments. Combine small segments into larger groups:
Use the Categories section to highlight segments.
Use the Color section to highlight groups.
Do not use pie charts to show changes to proportions over time or for precisely comparing data by category.
