Dynamic control of Scatter chart as Trellis

[#1]

Hi,

I've attached a sample QlikView showing a scatter chart viewed in a trellis formation.  I need to be able to indicate somehow one of the four corners dynamically in each trellis location.  It doesn't really matter what method I use, whether it's controlling reference lines along the right/left, top/bottom, added text in the proper corner, adding adddtional values in the corners (see below), or even have a background gradient point to a corner. The main consideration is that the corner position is always shown independent of any dimensions that have selections.  Any help would be appreciated.  My preferred method would be using background images dynamically, but it seems the Dynamic Images checkbox is grayed out when you switch to a trellis chart.

Thanks,

Barry
