Why do I not see data in my search's visualization?

[iiooiiooiioo]

I have this search:

host=app-dev-001 rehire OR terminating OR new_hire OR "changes supervisor" | convert timeformat="%Y-%m-%d %H:%M:%S" ctime(_time) AS date | sort date | table date rehire term_user new_hire super_change

and I get results:

date    rehire  term_user   new_hire    super_change

But when I click on the visualization table I get an empty graph.

My understanding is that visualizations plot numerical values. For something to show up in your visualization, define what you need to visualize, and extract - or generate - numerical values representing that.

Doh you are exactly right. I will modify my search to generate numerical counts.

I am using this search now:

host=app-dev-001 rehire OR terminating OR new_hire OR "changes supervisor" | convert timeformat="%Y-%m-%d" ctime(_time) AS date | stats count(rehire) count(term_user) count(newhire) count(super_change) by date

Cool! (Please mark my answer "accepted" if it worked for you.)
