Multi-value variable

[muhammedbasilek]

Hi,
I'm new to mongodb-grafana. I'm trying to create variable and I'm facing some issues. please anyone help me to sort it out

1. Cannot create query variable, it not showing preview of values. my query is db.status_all.aggregate([ {"$group": { "_id": "$client"}}, {"$project": { "client": "$_id", "_id": 0 }} ] ). it will give all client values but in preview it not showing
2. If i try to create custom variables it is working, but still multi select is not working, after enable multi select it will show only for one client value, it showing no data for the 'All' option and for more than one value option as well. I tried these ways both are not working a. {"$match":{"client":"$client"}} b. {"$match":{"client":{"$in":["$client"]}}}

I used like this {"$match":{"client":{"$in":[[clients:json]]}}},
but for the first issue still I couldn't find the solution!!
