Grafana tries to solve this by allowing each data source plugin to inform the templating interpolation engine what format to use for multiple values. +Note that the *Custom all value* option on the variable will have to be left blank for Grafana to format all values into a single string. + **Graphite**, for example, uses glob expressions.
