I am using a Line Chart in my visualization where in Y axis is shows a Time spent by a process (End Time - Start Time ).
The Chart works fine for last 24hrs or last 30 days data sometimes. But If I increase this limit to 10 weeks or so on... The values are shown in negative.Since the values are time stamp I dont think so they will go in negative (also my query (End Time - Start Time ) I have checked correctly.
Under buckets I have a aggregation on term and an order by metric: Y axis data desc and size as 50.
If I change this size to 29 or some times 25 then I get a proper graph. Or else it goes in negative.
I am using Kibana 5.1.1.
Kindly help with this.
