How to Query to display one data field on Graph

I’m using elasticsearch, logstash, and getting the data from a csv file.
I cannot figure out how to query to display one data field (i.e. High) from the csv file in relation to another data field (Date) which is of type string.
I tried selecting any of the modes under X-axis but nothing happens when I do.

Is there a way to have another data field as the X-axis?
How can I have the graph plot all of the High data field points, instead of count, avg, etc.?

Thank you!
