I don't understand really what you want.

I plan on doing this, but it is some work to go through the VGChartz-data to get all the old sales. So it will take some time.

Make stacked area charts with a different line for each console. Y axis labeling (EDIT: Screwed up here, I meant X axis) is in years. Does that make more sense? (Area charts are line charts with everything under the line filled with a certain color. If you use a stacked area chart it combines the lines in a cumulative fashion).

Here, a picture can explain a thousand words.

If I understand you right, it is different data than the one I gathered for this charts. You want yearly data for the consoles, right?

OK, the image makes it more clear. You want the data stacked. That is possible, but makes it hard to compare each one.

Right, but you already have a beautiful graph that compares each one. This would show overall market trends which is something I think would fit well with waht you already present.

You want this?

Should I add it to OP?

Oh derp, I just realized I made an error in one of my previous posts. I wanted you to label the *X* axis in years, so the graph would start in 2005 and show the console sales to now. :P So the Wii U would only show up near the end of the graph. Sales of all consoles wouldn't be launch-aligned but rather displayed on a weekly/monthly basis across years.

I will not do that on a weekly base - that means extracting practically all hardware-data from vgchartz. I will not do that by hand and don't feel like writing a program for that. I can do that for yearly sales though. Looks like this:

I wouldn't add this to OP though, as this will change not noticable on a weekly base. We can look at it again next year.

Edit: I realized I named this wrong, it's not cumulative. I can't think of the right name at the moment.

looks like a mountain with water in the bottom :))

OK, updated with the numbers from crissindahouse global up thread: http://gamrconnect.vgchartz.com/thread.php?id=152907&page=1

WiiU is dropping in weekly sales below X360 and PS3 now. Remember, PS3 is at that point sans europe.
