I have read the posts and reviewed Wiki comments on this topic and understand the "work-around".

The feature request is to be able to force the size of the Price Pane so when you minimize other Panes the Price Pane does not fill all the available space. It's as simple as having a "Hide The Pane" option on the Price Pane. For Pairs trading you care about either both charts ( easily done in WL), or just the related Charts like Ratio, Spread, and indicators for Ratio.
Forcing one Pane other than the Price Pane to max height does not help with multiple chart views.

Thanks for considering!

I guess you're talking about this Wiki "workaround"?

I want to chart an indicator, but without the stock price. Can I hide the PricePane?

Just to make it clear for other users who'd stumble onto this thread.
