Yes, I had a customer that thought I was using 1 pixel wide vertical columns
instead of a filled polygon in one chart. I was applying a data smoothing
algorithm so they were wondering why the line didn't look smooth. I had to
explain that I was smoothing the data and not the line but they weren't too
impressed. I think this is quite an important feature. The lack of
anti-aliasing means that Rev can't really claim to be a multimedia tool and
also is a disadvantage for charting etc in data management and
representation apps.
