parallel coordinates graph help qvdocs/Insurance.qvw

[#1]

Hi,

I’m trying to recreate the parallel coordinates graph from
this example dashboard.  I’ve successfully managed to go this, but I’m
stuck on two things. 

1. All my lines are different colours.  How to
   you programme the colours to remain for gender (or another variable?)
2. I don’t understand the line percent syntax – can
   you help explain this to me?  I’m assuming it determines the line
   thickness?

    =SUM(IF(Type = 'Claims',[Invoice
Count],0))/max(total aggr(SUM(IF(Type = 'Claims',[Invoice Count],0)),
CustomerMix,[Customer Gender],[Customer Marital Status],Product, [Posting
Year]))

Thanks!
