Grafana Using the second y axis

How do I use the second y axis, secondYAxis function does not work

You can switch any series to the second y axis by clicking on the colored line to left of the series name in the legend below the graph. Alternately, use the “Display Styles” > “Series Specific overrides” to define an alias or regex + “Y-axis: 2” to move metrics to the right Axis
