How to change the line chart in grafana with multiple variable variables

Hi,

How to change the line chart in grafana with multiple variable variables?

When I select a variable, the chart will draw a polyline, and if I select multiple variables, it will draw multiple polylines.

ex:
choose one variable:

choose five variables:

All the above displays are realized within the scope of one chart.

Thanks!

I have an idea that I think i can use the variables in Query editors.

When i add a new variables, then the Query editors will add a new Query.

But i don’t know how to do it?

Nobody can help me ? :sweat_smile:
