Documents that I index into kibana have a field, "action" which can either have a string of the action performed or "no-action".
My x-axis is a histogram on field "age" in each document (multiple documents can have the same value for this field)
For each bucket created, in Kibana I want to graph a metric of :
number of documents having no no-action / total number of documents
How do I go about performing the above summation then division and plot it on kibana (as y axis value)?
