Regarding panel variables, is it possible to use a variable value from one query in another?

Following should work

SELECT DISTINCT(JSONExtractString(labels, 'k8s_node_name'))

FROM signoz_metrics.time_series_v2

where JSONExtractString(labels, 'region') = {{.region}}

@Srikanth Chekuri Thanks for the response and yes it's working now. Not sure what I was doing wrong. Thanks!!
