Sorry to nitpick but my geeky nature just won't let it pass...That is one awful graph, it tells you absolutely nothing. I assume it's total sales on the y-axis and time on the x-axis but one is not labelled and the other doesn't specify the units. Also a source for those figures would be good. I appreciate it must seem like I'm being a total jerk but I assure you it's just as I feel compelled to point it out...good data presentation and citing is important if you want to keep people accurately informed
