Tableau Heat Map

Tableau Heat Map is used to display the data along with colors. We can create a heat map using one or more Dimensions member and Measure value. Heat Map in Tableau will help compare the data by their color. For instance, How many products are fallen short, and How many products are above our expectations so on.

In this article, we will show you how to Create a Tableau Heat Map with an example. Please visit Connecting Tableau to SQL Server article to understand the configurations. And the custom SQL query we are going to use for this Tableau Heat map report 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]

Next, Drag and Drop the Sales Amount from Measures region to Text Field present in Marks card as shown below
