Okay, or by another name… a 100% Stacked Bar Chart, yes?
That’s certainly possible with a combination of Glide + quickchart.
In fact, I posted an example demonstrating creating a Stacked Bar chart a while back…
The extra math required to make a 100% Stacked Bar should be reasonably straight forward with Glide computed columns.
Note that the only reason that I’m encouraging you down this path is that it will potentially save you a few manual steps, and your charts will appear instantly in the app.
