i am relative new to Grafana and i have a small issue, wich possibly is a bug in Grafana.
I am using MySQL and i want to dynamically show certain colums of my datatable. My first thought is to make a variable for this. Unfortunatly when i set it to be “multi-value” this is not working correctly.
This is my variable:
this is my SQL query.
If i not set it to be multi-value, everything works fine.
Another strange thing is, when i set the variable to muli-value and select all possible values and then deselect “multi-value”, grafana will still show all values as selected. In this case also it shows me the correct graph for each of the variables. This is exactly what i want, but it unfortunatly only works when i havent “multi-value” selected.
Thanks in advance and kind regards
