Heatmap
A Heatmap uses color to compare values across two categorical axes, making high, low, and clustered values easy to identify.

Field Settings
Use a field’s settings menu to configure supported rename, aggregation, sorting, filtering, relative-date, and formatting options. See Configuring Data.
