Pie chart in Yandex DataLens

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.

8. Drag a measure from the dataset to the Measures section. The values will be displayed as pie chart areas.

RecommendationsRecommendations

• 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.

  Example of combining segments in a chart

  Source table

  ProductSubcategory	Sales
  Beauty and health products	11M
  Kitchenware	34M
  Kitchen products	23M
  Detergents	22.5M
  Health and beauty equipment	35M
  Non-essential goods	23M
  Cleaners	21.5M

  To combine multiple segments by the ProductSubcategory field into a joined group:

  1. 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
     

  2. Drag the new field to the Color section.

  3. 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.
