I used AppViz for most of the charts (it's a great program to keep track of your sales and visualize them in different ways). The chart with colors it's just generated from Pages since I had to do some aggregating of the different IAP items myself.
You're right about the lack of labels (that's how the program does it), but I made sure it was explained in the sentence following the first chart. I wanted to stress that the vertical axis is profit in US$ and not unit of sales (since Flower Garden is $2.99).
