Plotting Apple Sales Trends

Kieran Healy, following up on Dr. Drang’s post on the iPad’s sales slump:

Dr Drang put up a characteristically sharp post looking at sales trends in Apple Macs, iPhones, and iPads. He used moving averages to show long-term sales trends effectively, and he made a convincing argument that iPad sales are in decline. I ended up grabbing the sales data myself from barefigur.es and more or less copying him. Instead of a moving average, here’s a plot of the trends showing the individual sales figures with a LOESS smoother fitted to them.

Truly fascinating visualizations of Apple’s sales trends for iPhone, iPad, and Mac.
