Pie chart
Written by
Updated at October 23, 2024
This chart shows a proportional relationship of different categories to a total using circle segments (sectors). The entire circle area is 100% and corresponds to the sum of all categories. The area of each segment corresponds to the percentage of a category in the total amount. Pie charts are a good choice for demonstrating proportions of a small number of segments.

Creating a pie chart
To create a pie chart:
Warning
If you use a new DataLens object model with workbooks and collections:
- Go to the DataLens home page. In the left-hand panel, select Collections and workbooks.
- Open the workbook, click Create in the top-right corner, and select the appropriate object.
Follow the guide from step 4.
- Go to the DataLens home page.
- In the left-hand panel, select Charts.
- Click Create chart → Chart.
- At the top left, click Select dataset and specify the dataset to visualize.
- Select Pie chart as the chart type.
- Drag a dimension from the dataset to the Color section.
- Drag a measure from the dataset to the Measures section. The values will be displayed as pie chart areas.
Recommendations
- If there are more than 4-6 segments per chart, group the smallest of them as Other. A larger number of segments overloads a chart and makes it difficult to understand the data.
- You cannot display negative and null values on this type of chart.
- Do not use pie charts to show changes to proportions over time or for precisely comparing data by category.
