You know... people REALLY USE the "%" symbol when making charts. We'd like to be able to use it when making live marker symbols, but we can't because that is the reserved symbol for markers. NO ONE would use a tilde since it can't be represented as a data point. Please change this and add functionality to add a suffix to numbers when used in a column marker. You REALLY need to bring charts into the 21st century... I feel like I'm still working in 1999.
