A Tableau Pie Chart is a graphical representation of data in the form of a round circle divided into different categories or pies. Each pie represents the category, and its size is directly proportional to the numerical data. Pie charts are easy to represent the high-level data in a more meaningful way.
Pie Chart in Tableau is useful to display the Sales by region, Countrywide customers, Sales by Country, etc. These are also helpful in the dashboard design. For example, we can use the pie chart to display Country wise sales and then use the Action filters to drill further down.
This article shows how to Create a Pie Chart with an example. For this, we will use the Data Source we created in our previous example article.
How to Make a Pie Chart in Tableau?
To create pie charts, first, Drag the Sales Measures to the Columns shelf. Since it is a Measure value, the Sales Amount will aggregate to a Sum(default). Next, Drag and Drop the English Country Region Name from Dimension Region to Rows Card. Once you drag them, the following bar chart screenshot will display.

Once you select it from the Show Me window, the plot will display with different default colors.
Please use the Size option in Size Card to expand or Shirk the Pie chart.
If you observe the above screenshot, it provides the perfect results. However, we are unable to identify the difference between the Sum of Sales measures in France and Germany within the circle. To resolve these situations, We have to display the Data Labels.
Add Tableau Pie Chart Data Labels
To add Pie chart labels, Please drag and Drop the Label marks values from Dimension or Measure Pane to the Label card in Marks Card.
In this example, We want to display the Sales Amount as Data labels, so Drag and Drop the Sales Amount from the Measures region to the Labels option.
Pie Chart allows us to add Multiple Measure values as Data Labels. It can be handy when you want to compare the Total Sales against the Profits by Region. To do this, use the above technique to place the Yearly Income.
