That graph is lacking numbers, the thread title says 'barely any money' which is clearly not the case judging by the graph, the graph only takes into account revenue from additional content and not selling the game itself, and the PC version was late by a pretty long while. Basically it sounds like the title and the content of this thread don't match at all, and they're both ignoring the fact that the game was released much later on PC.
And despite the late release, according to Steam Spy the game has about 5.6 million owners on PC, which is a lot of revenue. Assuming $30 of profit per copy, that's a total profit of $168 million. I wouldn't call it 'barely any money'. Of course that's not an accurate figure, but should give a rough idea about what we're talking about here.
