Muti databases in Influxdb

Hello,

InfluxDB shell version: 1.6.2

show databases
name: databases
name


BASE1
BASE2

I would like under Grafana, to combine in a graph the measurements of the 2 bases
BASE1 = measurement_A / counter1
BASE2 = measurement_B / counter2

In Grafana is it possible to combine the 2 counters: counter1 + counter2
But in Grafana, you can only choose one Data Source

Create a BASE3 and copy the 2 measurements ?

thanks in advance

This isn’t possible with InfluxQL however if you enable Flux you can do this by querying multiple buckets
