I'm trying to create a heat map with `monitor.status` reported from heartbeat, but the "Aggregate with" drop down remains stubbornly empty. I only have this issue with heat map as a vis, it works for others. Is this a genuine issue or is heat map somehow incompatible with a String as a Top Hit aggregation?

Forgot to add, using Kibana 6.5.0

Hello,

That's very interesting. Can you please check what is your mapping type for monitor.status?

To expand on this, it seems that I cannot get _any_ string field to work with the heat map, only numbers.

I also upgraded to Kibana 6.5.4, still can't make it work.
