Is it possible to have independent x-axis ordering within x-axis groups in graph builder?

[#1]

In the attached data table the saved script plots the chart below.

I want the x-axis parameter bars to change in order with the highest number of fails appearing first within each week (i.e. a Pareto type plot within each week)

I created a FailOrder column for ordering within each week, but it does not seem to do what I want. 

Is there a way, via JSL, to have the order of the parameters (Para) in ascending order of the number of fails (FailCount) within each week independent of the x-axis parameters other weeks?  

(I do not want to use the Page option nor do I want to transpose the data table)
