I have tried passing something like this, but didn’t work:
what is your version of grafana, data source
I checked about this plugin and it seems to be a community plugin as described on the plugin page (that means, it is not maintained by us).
I see that they provide some examples of using variables and also on their official GitHub page under issues, can search for variable-related questions.
I hope this is helpful.
Thanks @usman.ahmad and @yosiasz, I have already resolved this issue.
Good to hear that you sovled it @abhinavanandpnbe
We will encourage if you can post your solution so that the other community users who are using this plugin can use it if they have similar problem.
