Hi
I was looking for progress bar, but ended up making one from canvases, which I've attached.
It has an interesting aspect where regardless of the size of graph-on-parent it displays complete, i also had to fiddle a bit to get $0-variables to work in the canvases.
I'd be interested to know if it is made correctly as I am fairly new to Pd
