Heatmap charts use a comparable color-coding system to represent data values. However, heatmaps distinguish themselves because they do not use size to measure data, instead requiring an additional attribute to properly map the data.
Heatmap charts do not support conditional formatting.
By default, data labels are enabled for every value in heatmaps. To disable data labels for heatmaps, follow these steps:
Navigate to the heatmap for which you would like to disable data labels.
Select the Data Label panel on the right of your screen.
You can select the Display on chart option.
