Trouble Displaying Data From CSV File

I am using elasticsearch and logstash to try to display data from a csv file on grafana. I cannot figure out how to get a graph of anything, but more specifically I want it showing one column’s data (i.e. High on Y-Axis and with Date being on the X-Axis).
I cannot even get a graph for any of the data (only table view), newbie! I do know that everything is connected correctly because I can see all the data points when I select Raw Data format!
Here is the table view of the raw data

And when I try to change to Graph visualization, the error is “No field name specified to use for x-axis, check your axes settings”.
I am unable to select any of the options under the X-Axis. It does not fill any of the choices when I select.
