I have a SqlServer data with the following fields:
Time | Variable1 | Variable2 | Variable3
The VariableX data si numeric.
I’d like to create a Grafana custom Variable with values Variable1, Variable 2, Variable3 with multi selection enabled so to plot a graph with one or two or the three different values.
How to do this?
To plot different vales on the same plot I think the only way is to have different queries A, B, etc with divverent value fields, and I don’t know how to split the resulting variable value when I have multi selection enabled.
Is there a format option selecting only single multi variable items?
