Indicators inside Charts

Hey! this is my first post so I hope that it correlates with the best practices in the community.

I have created delta indicators with go.Indicator, but I can’t manage to find anywhere any examples or documentation of what I am trying to get.
Here’s an example of such a graph I am trying to produce:

Any ideas?
Thanks :pray:
