I add Split group in Buckets in Metric of Kibana. Aggregation is set to Terms. And I enable 'Show title'.
The values of Field are used as the name of Show title. (0, 1, 2)
I want to change the name. For example, 0 to A, 1 to B, 2 to C.
Is it possible to change the field name of Show title using JSON input?
