Yes, the progress bar of a disk defrag is what I am looking for. The picture control approach sounds interesting. I am not really familiar with it, can you point me to the right direction? thanks!
I don't know why we'd consider intensity graphs or picture rings when a very simple boolean array would work. Attached is an example of how to do the bar I explained earlier.
Thanks. I learned a lot about picture control.
This array would work for 100 elements, and I think it is a great idea.
