Drill Through - Help with Filters?

I'm curious if anyone can help me with this problem.

I created a scatterplot with items that have been created. The y-axis is the amount of hours it took to build, and the x-axis is the number of weeks that have passed since beginning the project. On this page I have filters for multiple weeks, the type of product, and the specific product.

I am trying to create a drill through page that shows a line graph showing all weeks for one specific product. The problem I am facing is that when I drill through on a specific point, it only shows that product for that particular week and not all the weeks.

Any ideas?
