Tableau Bubble Chart

Tableau Bubble Chart is used to display the data in circles. We can define each bubble using any of our Dimension members and size by Measure value.

Bubble chart in Tableau play a significant role while creating Maps. For instance, we can use them on top of the Map to display the Sales by Postal code, etc. In this article, we will show how to Create this using Custom SQL Query. So, visit Connecting to Server article.

       Fact.TaxAmt,

   INNER JOIN FactInternetSales AS Fact 
      ON Prod.ProductKey = Fact.ProductKey 
   INNER JOIN DimSalesTerritory AS Terry 
      ON Terry.[SalesTerritoryKey] = Fact.[SalesTerritoryKey] 
   INNER JOIN DimGeography AS Geo 
      ON Geo.[SalesTerritoryKey] = Terry.[SalesTerritoryKey]

First Approach to Create Tableau Bubble Chart

In this example, we are going to create a Tableau Bubble Chart for State dimension against the Sales Amount size. First, Drag and Drop the State Dimension from Dimension Region to Text Field in Marks Shelf. From the below screenshot you can see the available State names in the report

Next, Drag and Drop the Sales Amount from Measures Region to Size Field in Tableau Marks Shelf.

Once you drag them, the following screenshot will be displayed. By default, the Desktop is displaying Tree Map

To change the Default TreeMap to Bubble Chart in Tableau, we have to change the default Automatic option in the Marks Shelf. Please expand the drop-down list and change the Automatic to Circle.

Once you changed, Tableau Bubble Chart will be displayed with State Name as Text filed and Sum of Sales Amount as the circle size. From the below screenshot, you can see that the Size of a California State is bigger than the remaining states because the Sales Amount is higher than other states.

Let us add the Sales Amount to the Text field as well. By this, we can see the State name along with the Sales Amount. To do this, Please drag the Sales Amount from Measures region to Text field present in Marks Shelf

Let us add color to our Tableau Bubble Chart. We can do it by dragging the Calculated field Profit to the Colors field in Marks Shelf.
