What do you mean Kirby?
You mean the colours for the 500k/1million seller etc?
Or do you mean the old line graphs with the tables of weekly (well monthly for America back then) sales?

I certainly prefer the new graphs, perhaps the lines could be a little thinner so it is clearer, or better still, have oit so that when you roll over the point to get the exact number, it should display it in that lines colour so you know which console it is refering to if they are close for the week.
