X-axis order question with related data

[Joost Miltenburg]

LS,

I find charting confusing. Anyway...

My goal is to do a product year over year comparison on how many times it has been sold given a date. 
Two products can be picked and a reference date will be entered. A product has a date in it so it will be unique. That's why I am comparing two products

I found the related table example in the training series and I got it to work. However, the 2016 product comes in the first column and the 2015 in the second. I would like to change that so that 2015 comes first. I've tried sorting the relationship, that didn't work.
