Redesigned history charts ("Patterns")

[lmerriam]

Right now our history shows every trackable a user is tracking.

• It's hard to see correlations between charts that are not next to each other
• Loading literally hundreds of trackables can be very slow (or even crash the app in some cases)

Proposed solution: let users choose sets of trackables that are grouped together into charts called "patterns".

Behavior:

• Display the user's patterns
• Display a "legend" showing the trackables in each chart
• Tapping on a pattern shows a tooltip over the nearest day
• Change navbar
• Set color for charts

Requirements

• Chart is responsive to different screen sizes
• Chart accepts touch input

Updated screenshot showing multiple patterns and date selection:

Tapping on either date would bring up the same datepicker we currently use. Let me know if there is a simpler way to do this!
