Area selection

Would it be possible to select an area between two points and apply a different color? Like the MacOS defaut Stocks App?
So far I have only been able to highlight a single point.
Is it something doable with the library?

Thannks!

Start by reviewing the library's existing single-point highlighting and selection behavior. Clarify which chart types, interaction rules, and color behavior the requested two-point area selection should support. Done means the intended behavior is specified and implemented with coverage for the relevant selection cases.
