Excluding field which return null in Kibana

[Saket_Kumar]

I am retriving field1 on x-axis and which returns null and values. I want to show only those which has some value than which return null.

I see Exclude Pattern in Advance. Can it be excluded from there?

I don't think you can do that from the exclude patterns, but you could combine this visualization with an "exists" filter: Where to add a missing filter in this Kibana search
