Unable to see Time and Data of InfluxDB in Grafana Graph

I have a measurement called "testtable" where I have kept my testcaseIDs in 1 column, time in 1 column and latency which is a value in one column. I fetched latency from the influxDB query in Grafana.

I see the output in the table format. I am unable to see the data in the timeseries graph. Also, how do I consider the time data read from the influxdb as my x-axis and y-axis as Latency with the graph showing the data points.

Solution

Your latency is a string, e.g. 1.24s - you can't graph strings in the Grafana. Only numbers e.g. 1.24 (integers/floats) can be graphed. Also InfluxDB doesn't have column, but it has fields and tags. Make sure your latency is a field.
