Hello,
What kind of regexp does this color formatter support for numericals? I'm don't have a lot of knowledge regarding regexp but something like [5-9][0-9] or ([5-9][0-9]) works in online regexp checkers but not in Kibana.
Setting static values does not appear to work either (e.g. my index has a value 50.0 and I put 50.0 in the field formatter).
The fields are mapped as numbers (half-float).
I have no problems using various regexp to match string values.
