Maybe try to use Graphite as additional query API for influx. We switched to Influx from Graphite but some queries where unable or cumbersome to translate into Influx query language (especially inside Grafana). In our case we use Graphite-api with a Influx plugin instead of Graphite's own frontend. https://github.com/InfluxGraph/influxgraph

It's possible to write raw queries in Grafana by changing the query edit mode.

True, but even then there are some queries you can't do which graphite can. And you loose the nice editor grafana offers.
