How to create a Heatmap chart in Excel
Excel does not provide a chart template for heatmap charts yet. The simplest way to create a heatmap in Excel is to add Conditional formatting to the spreadsheet cells.
To create a heatmap, do the following:
1. Select the data.
2. On the Home tab, in the Styles group, click the arrow next to Conditional Formatting..., then select Color Scales and then click More Rules...:
Note: You can also choose the New Rules... from this drop-down list.
3. In the New Formatting Rule dialog box:
- Under Select a Rule Type, be sure that the option Format all cells based on their values was selected,
- Under Edit the Rule Description, on the Format Style dropdown list, select the 3-Color Scale option and then select the colors for Minimum, Midpoint, and Maximum values:
- Click OK.
