Now we will see how to build a heat map in Power BI visuals.

How to Build Heat Map in Power BI?

To build Heat Map, we need a certain set of numerical data. Below is the sales happened data in different cities of India.

Power Bi Heat map (Excel data)

Since this is our first try to build a heat map, let’s start with simple data set only. Copy and paste the data directly to Power BI, or you can copy the data to an excel file and then import it to Power BI as an Excel file reference. You can also download the excel workbook from the below link, which is used for this example.

I have directly uploaded the data to Power BI.
