Resample returns "No data"

Grafana
1

Grafana v7.5.7 (91de51771c)

My problem: I have several metrics in Azure SQL that are misaligned in time.

What I want to do: I want to align the metrics in time.

What I did:

As expected, Grafana displays the misaligned metrics if I delete the Expression Query “b” and I just run the query “a”.

Once I add the Expression Resample “b” Grafana displays the message “no data”.

I followed the documentation Query and transform data | Grafana documentation

The problem seems similar to what is described in this old post from 2019 https://localhost:3000/t/expression-in-query/43325

The post does not offer the solution to this issue.

Hi @rmx

Expressions like resample are still a beta feature.

Do you think you could accomplish something using transformations instead? Or performing operations on the db side?
