Adding a second plot to a new panel in an indicator

I think you can do something like this using an add on. I have the main indicator and an additional indicator in the addons. This allows me to sync some values in the main indicator to a different indicator. If you look at the screenshot you can see the main chart and a bottom histogram. You’ll have to add both when selecting indicators.
