Tracking seat holds in Analytics

I’m hoping to find some advice on how to go about building an Analytics chart that will give me a stacked bar chart showing paid, reserved unpaid, held, and available seats in one glance. I built the paid and reserved unpaid portions no problem, but cannot figure out a workaround to count held seats in the same chart. I’ve put a screenshot of the chart in progress below in case that helps demystify what I’m trying to do.

 

If anyone has any tips or advice, I’d be very grateful!
