If I had a section of my JSON input into ElasticSearch that looks like below, and I am able to access categories.category.keyword and categories.totaldur is it possible to create a visualization with the different categories and their totaldur?
"categories":[{"category":"TB","totaldur":55},{"category":"CPB","totaldur":568},{"category":"PP","totaldur":23}
That's currently not possible because it would require nested fields that are not supported yet by Kibana. You can denormalize your data and expand each document into n documents with each document just containing a single category, then you can use the regular visualization capabilities of Kibana.
