I am working with an elasticsearch data source.
I would like to both split by one field and group by another field.
The group by field has a very high cardinality over time so I cannot use the default group by by I can use a transformation to group by.
My problem is that to achieve the split I am currently doing multiple queries, only the frames are named 1, 2, 3, 4 and so on.
This means if query 2 does not return data the queries are reordered numerically. More importantly when I visualize the data the legend reads:
- blah 1 (mean) - blah 2 (mean) blah 3 (mean)
Which is not very descriptive. If I do an outer join I can organize and then rename the key fields, but due to the fact I may not always get the same data and the fields can be renumbered that doesn’t really work.
Ideally I would be able to name the query and the named query would name the frame and that name would then be what gets applied to each field rather than a number. But today that does not seem possible with the existing plugin.
Is there a way to achieve this?
