How can I see a comparison of book/store/country sales instead of the total for all books?

The default stacked-bar "total" sales charts make it easy to see how your total sales are changing over time while still giving you a sense of how each book, store, or country contributes to that total, but it's hard to compare them accurately by simply eyeballing the bars. To help with this, BookTrakr includes a comparison mode that switches the sales charts to a non-stacked line format. To activate it, simply switch the picker labeled (1) below to "Comparison" instead of "Total".
