Unable to add new field from calulation/binary transform a series from CompareQueries

[fenneh]

What happened?

I believe this is a similar issue to AutohomeCorp/autohome-compareQueries-datasource#41

I believe when using CompareQueries it breaks the ability to add new calculated fields via Grafana's Transform Data option.

If I toggle CompareQueries off the series generated by the transform show, if I toggle it back on the transforms stop.

The reason I'm attempting to do this is I have

• Query A - CPU Usage for today
• Query B - CompareQueries doing a time shift of 1d
• Grafana Transform - Diff the two queries

What did you expect to happen?

The diff to be displayed

Did this work before?

N/A

How do we reproduce it?

1. Create Query A
2. Create Query B which is a CompareQuery of Query A but time shifted
3. Use Grafana transform to Add field from calculation and do a math operator on the two series

Environment (with versions)?

Grafana: 11.0.0
OS: Windows
Browser: Edge

Grafana platform?

Docker

Hi, @fenneh thanks for your issue. According to the docs on Grafana， since the compareQuery plugin is totally a frontend plugin, so it's unable to support the feature which only works in backend plugin.

Calulation and transform are the feature only works in backend plugin~

@ShelbyTang For frontend plugin it is unable to use the backend feature, I will try to do some development for this feature if free these days
