Hello. I've discovered for myself an issue with Kibana that seems to be a long-running issue on GitHub: Including missing value as a bucket on piechart and other chart aggregations.
I've found the documentation of the "Advanced" features to be sparse. I had hoped that perhaps I could use the JSON Input feature to simply add on a bucket for "missing" values.
How do I do this?
I like a lot of features about Kibana but think the documentation leaves a lot to be desired. Perhaps a "gallery" along the lines of what matplotlib does?
