Dual Waterfall

I'm running into an instance where I know what I want my graph to look like, but have no way to get it there.

What I have is two separate sheets, one for billing and one for expenses. The billing sheet has the date and the billed money totals, the expenses has the dates and cost for things ordered. I'd like to track each one on the same graph, with the X axis being the date. Each different line, the billing and expenses, should add up as the dates progress. It seems a waterfall graph would work, but I initially thought of a game flow graph on how it should look in the end.

Either way I can't get any graph option to look like either of those options.

Makes sense, since the basketball score is a running total itself. Got that to work, thanks.

What I am running into now is getting the two lines to use their own dates. I can get the billing line to work, but once I put in the Expense line, it just uses the dates from the billing line.

Scratch that, I figured it out.

You can select a different X-axis series in Excel. But I was translating this into google sheets and sheets doesn't allow for multiple X-axis series. But a google search got me a work around.

Thanks for your help!

I usually ask here first, as I end up using both. And if things don't work out I'll keep in mind that I can post in another subforum.

Thanks again!
