Providing context over time

The bottom part of the screen shows a bar chart with the current and previous months spending. Tapping a category (or revealing the Cash slide) would actualize the timeline so users would understand longer-term trends. Tapping on a previous month on the timeline actualizes the category chart, making it easy to go back in time and find specific transactions. Bonus: we were able to retrieve transactions for up to 90 days back when users added a new account, so the timeline feature was valuable even for new users on their first day with BillGuard.
