How to add 3rd data dimension to Box and Whiskers plot

[Drizzt]

I want to be able to plot multiple parametrics in a box and whisker format, then overlay the box with color gradients representing yield against the parametric distribution.  I am currently accomplishing this task manually using a spreadsheet (see attachment).  It allows the viewers how the data is distributed for each parametrics and at the same time see how the yields react.  I know the distribution part is easy with box-and-whiskers type plots, but I have not seen any examples with added dimension of yield, etc.  Is this possible?  Thanks.
