In order to calculate the percent of two series with wildcards I need to use some of the reduceSeries(),mapSeries and groupByNodes function.
Although I do see the functions defined in gfunc.ts I do not see them in the drop-down menu when defining queries for panels. I tried to define/update graphite version in the datasource (as suggested by one post) but it does not work. I edited as well manually the query but I do not know if the error is because of function not supported or the query is wrong (the query Inspector does not work/help either).
Can anyone point in which grafana versions are the above functions supported ?
Grafana version i am currently using is 6.6.2 and the datasource is Graphite.
