Grafana, how to choose which column for axis in Timechart?

Question

I am using Grafana to perform a Log to Metric query using an Azure Data Explorer datasource, that gives me a result like this as a table:

This comes from this query:

Log
| where $__timeFilter(TIMESTAMP)
| where eventId == 666
| summarize count() by bin(TIMESTAMP, 15m), Region
| order by TIMESTAMP asc

When rendered as a timechart in AppInsights, it renders perfectly like this:

However in Grafana, this perplexingly renders by the Count_ column, not using the obvious Regional breakout field:

My goal is to get an AppInsight's like timechart with multiple data series, within Grafana

Answer 1

I found my answer! It turns out I was rendering the data as a Table, using the Grafana query wizard here.

Once I changed that to TimeSeries, it all just worked!
