That makes it more complicated. An expedient solution would be a button to land the user on a page which has two separate waterfall charts and then the users can kind of visually compare.
But I think if do you want it all on one graph then I think it can be done by having a table of weeks and then you would have to have a two formula queries to calculate your running totals. The syntax for those formulas is a little more complicated so I'm not sure I could just whip that up quickly on this community forum. If you want it badly enough you would have to contact me directly for some one-on-one consulting assistance or else hope that someone else is willing to help you on this forum with the formulas for those Formula Queries.
