I have a question for aggregation on Kibana, the context is following as
- Line chart
- Bucket: Date Histogram
- Bucket: Split series on field A
- Bucket: Split chart on field B
- Metric A: Count
It means a list of line charts visualize a count of each field A on each chart that split by field B by a custom interval.
=> How to add one more metric to count total of field B on each chart, it mean add one line in chart with name is "total B"?
So you're saying you'd like one line in each chart that's just a simple flat line showing the total count of that chart?
Unfortunately I can't really think of a way to do this. The metrics are calculated based on the buckets, which means if you use a date histogram, the total will be calculated only on the given bucket, not across the entire range. I think the closest you can get is to use timelion and to use .static, but I don't think it can be dynamic
If you want, you could submit a feature request for this on GitHub.
