Ratings: Track a title's rating history

dear guys ; my quick question is, written below: why don’t you add a link on a film page’s rating bar(xxx avg. points/ 10 and xxx points/ metascore) which allows us to see/ track the film’s rating/points rated/ given by the members from starts very 1st beginning and changes every thousand votes, like a graphical line, with this way I assume we can understand how it went from it start/ released til now? thanx and regards ahmet
