The tableau Tree map is used to represent the data in Rectangle Boxes. We can determine each rectangle box using any of our Dimension members and the box size by Measure value. Treemap in Tableau is very useful to display the most massive data set information in a small data region. In this article, we will show you how to Create Tableau Treemap and the SQL Query for this is
SELECT Geo.EnglishCountryRegionName, Geo.StateProvinceName, Geo.City, Prod.EnglishProductName, Prod.Color, Fact.OrderQuantity, Fact.TotalProductCost, Fact.SalesAmount, Fact.TaxAmt, Fact.[Freight] FROM DimProduct AS Prod 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 Treemap
In this example, we create a Treemap for the State dimension against the Sales Amount size. First, Drag and Drop the State Dimension from Dimension Region to Text Field in the Marks card. Now you can see the available State names in the Tableau report
Next, Drag and Drop the Sales from Measures Region to Size Field in Marks card.
By default, Tableau Desktop is displaying TreeMap with State Name as rectangle Text filed and Sum of Sales Amount as the Box size. As you can observe that Box Size of a California State is larger than the remaining states because the Sales Amount is higher than in other states.
Let us add color to the Tableau Treemap by dragging the Calculated field Profit to the Colors field in Marks Shelf
Once you completed, the following screenshot will be displayed. State name Box with Maximum Sales will fill with Dark Green and Least Sales Amount with light green
Let us add SalesAmount and Profit values to the Text field as well. By this, you can see the State name along with the SalesAmount and Profit. To do this, Please drag the Sales and Profit from Measures region to Text field present in Marks Shelf
Tableau Treemap text format
To format the Tableau Tree map Data Labels, Please click on the Text field inside the Marks Shelf to open the below shown window. For now, we are doing basic formatting so, click on the … the button beside the text
Here, we added extra text Sales, Profit beside the < SUM(SalesAmount) > and < SUM(Profit) > and also changed the font style to Lucida Sans
See the Formatted Text in the Tableau Tree map
Create a Tableau Tree map example 2
Please press and hold the control key and then select the Dimension (s), Measure(s) from the respective region and select the Tableau Treemap from the Show Me window
Once completed, the desktop will create this for you.
