Pie Chart in Tableau is useful to display the Sales by region, Countrywide customers, Sales by Country, etc. Pie Charts are also helpful in the dashboard design. We can use the Tableau pie chart to display Country wise sales, and then use the Action filters to drill further down.
In this article, we show how to Create a Pie Chart in Tableau with an example. For this, we are going to use the Data Source we created in our previous article.
Please visit Data Labels in Tableau Reports article to understand the Tableau Data Source. If you want the Custom SQL Query Only for this report, then use the following query as your SQL Server Data Source
SELECT Geo.[EnglishCountryRegionName] AS [Country]
,Geo.[StateProvinceName] AS [State]
,SUM(Cust.YearlyIncome) AS YearlyIncome
,SUM(Fact.SalesAmount)AS SalesAmount
FROM DimCustomer AS Cust
INNER JOIN
FactInternetSales AS Fact ON
Cust.CustomerKey = Fact.CustomerKey
INNER JOIN
[DimGeography] AS Geo ON
Cust.GeographyKey = Geo.GeographyKey
GROUP BY Geo.[EnglishCountryRegionName],Geo.[StateProvinceName]Create a Pie Chart in Tableau Approach 1
First, Drag and Drop the Sales Amount from Measures Region to Columns Card. Since it is a Measure value, the Sales Amount will aggregate to Sum(default).
Next, Drag and Drop the English Country Region Name from Dimension Region to Rows Card. Once you drag them, the following screenshot will be displayed.
Now we have to change the default Bar chart to Tableau Pie Chart using the Show Me option. Please expand the Show Me window and select the Pie Chart from it as shown below
Once you select the Pie Chart from Show Me window, Pie Chart will display with default colors
Please use the Size option in Marks Card to expand or Shirk the Pie chart in Tableau
If you observe the above screenshot, the Tableau Pie chart is providing the perfect results. However, we are unable to identify the difference between Sales in France and Sales in Germany. To resolve these situations, We have to display the Data Labels.
Add Data labels to Pie Chart
To add data labels to Tableau Pie chart, Please drag and Drop the data Label values from Dimension or Measures Pane to Label option in Marks Card.
In this example, We want to display the Sales Amount as Data labels so, Drag and Drop the Sales Amount from Measures region to Labels option
Tableau 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
