Graphite Delay Function missing

Hi All,

I am using Grafana with Graphite datastore. I use Graphite functions to count difference between current and previous step. In Graphite I used ‘delay’ function but apparently looks like Grafana does not support it as it is not on the function(dropdown) list? Can someone tell me why?
I know that I can use editor and type it manually. But I wonder why this was removed from Grafana and is there any danger using this function typed manually? Or maybe is there another way I can calculate difference between current step and previous step?

Any and all help is much appreciated.

It is still there but we have added a version parameter to the Graphite data source and delay is 1.0.x function. Change this setting in your data source settings:
