Let's hold this for some time. We are going to change the way ClickHouse queries are handled so we don't have to worry about the column name details.

can you point me to what change are we expecting ? we can get this out if that change might take some time ? because currently there is no handling for clickhouse and promQL so either the default count appears or whatever values present in the QB appears.

There won't be any legend formatting for ClickHouse queries.

We can get this merged independent of the other changes that follow.
