Hi Math – Looking at the sample you sent, the left one isn’t what I was hoping for. When I look at the sample you posted, it starts with the “image” filled in the progress, then it “covers” the green ticks from the top down. The one on the right is what I was hoping for, where it starts with an “empty” bar, then adds the green boxes from top to bottom.
The one on the right uses a progress bar that does count forward, so it’s basically going from grey to transparent so that the image behind it can be seen.
Hopefully that makes sense – I’d tried the starting at the max, then stepping backward and it wasn’t quite what I was looking for.
