You can't make a chart without enough criterias to make it exhaustive. If the list is not exhaustive in a way, then the chart itself is not saying much than the sales data of each game. I mean if it's only meant to check the sales of a game, the simplest thing is to check the game in the games database, there's no need of a chart.
If you want to make it useful, you could for example restrict the totals chart to the current gen (DS PSP WII 360 PS3), since I guess the games list for these consoles is exhaustive
