Floating Bar, Min-Max, and specific data points

Hi everyone. I've been asked to put together a chart, and it's been baffling me for the past week exactly how to get it the way my boss needs it done.

I need to put together a floating bar chart that shows not just the min-max of each series, but discreet data points as well. The min-max isn't a problem, but getting all of the data points has not yet worked.

I'm wondering if there is a way to combine charts and perhaps show a line with the data points beneath each min-max bar? Seems unlikely, as I've never seen a combo chart like that before.

See attachment. It's dummy data, the actual charts will be MUCH larger (as many as 30 categories down the x-axis). And I realize I'd have to change the data to show variance to get the min-max to work probably. The original data isn't in an easy table like this either, I'll probably have to use some formulas to move it around. Plus it'll have to be automated when additional data is added later.

Much thanks for any ideas or help!
