This is the gif with what I've tried to do so you can double check:

@shahzad31 this was my bad, actually. I realized I needed to merge some changes from upstream before testing this one. That's why the other ones were okay but this one wasn't. Now it LGTM, thanks for pointing it out 😄

Just one question I've had is:

• When loading the third metric series there, it seems like the second series also starts loading, is this expected?

EDIT: Created #117275 with an "Enhancement label" after talking to @shahzad31.
