isNonNull function

Hi All,

Most probably this is a silly question but is there necessary to do anything special within configuration in order to use isNonNull() in grafana UI (grafana:6.3.1, graphite: 1.1.5)?

I’m asking because the function selector doesn’t offer this function - see attached picture.

Best regards,
V.

The solution is to set a correct version for graphite datasource.
