Oh, and you can't make a pie chart showing profits because profits can be negative, and pie charts can't show negative because they have to add up to the whole.
A profit chart would have to be a different type of chart.
In addition to that, we can't get a profit chart to compare to this (in the OP) data because it is showing revenue spent on the systems..... which means Nintendo's $10billion is made up of the money spent on people buying:
The Wii
The DS
Wii+DS games and peripherals.... it combines the revenue of 1st and third party, and thus would be immensely complicated to figure out the profits from it, if not impossible for things like multiplatform games (like how do you split the expense when it cost developers less to port a game that it would have with two built form ground up)
