Visualize by Column Names

Hi Team,
I created columns for my log file and i can see that in Discover but while preparing/visualizing bar chart i can't see "Company" as a field in X-Asix drop down list.

How can we see custom fields in the Dropdown list (X-Asix=>Aggregation=>Field)

*Company is a column/field name and it's available in discover _source


This is what a row looks like, i guess even after logstash filter "Column", entire row inserted as message?

What type of aggregation are you trying to do? Is the Company field indexed in Elasticsearch? Can you provide the mappings for this index or screenshots?
