I really like the Quality Rank, Value Rank, StockRank™ etc, but is there anyway to see them historically in a chart or graph? This way we can see how the company evolves over time base on those rankings.

You can get a stock rank graph for an individual stock from the stock report. Other than comparing the previous day stock rank with todays, I haven’t found another way to search for stocks that have improved/reduced their rank over any longer.
hope that helps
