That was Awesome IMO.
I have much to learn of AFL's capabilities.

Yes, how did you do that?

Has anyone successfully developed (or tried to develop) a generalized code for coloring an area defined by 3 or more lines?  For example, a triangle created with the zig-zag charting tool and a baseline.  Or a rectangle defined by two dates and two price levels.  Not unlike the "fill with color" option in Microsoft's Paint.  And along the same lines, is it possible to change the transparency of such coloring so that the underlying price bars, etc. are still visible?
 
Sounds like "mission impossible" with the AFL tools at our disposal but thought I would ask and maybe get "lucky."
 
Bill
