Dashboard: Revenue and visitors

[bummytime]

Discussion

For the purposes of the closed beta, let's implement a portion of the dashboard epic (#14):

As a store owner I want to see quick stats about my stores performance within the app so I can know how well my business is doing: revenue, visitors, orders volume.

From MVLP discussion: Provide a quick glance at important sales-related information that makes app users want to come back often to see how things are going.

Stick with the data available through the WordPress.com API, not through the Jetpack tunnel.

(There are more possibilities from the current iOS app we can draw from for future iterations:
Revenue, New Orders, New Customers, Top Selling Items, Processed Orders, Pending Orders, Held Orders.)

Work to be done

The above will require the following:

Networking Framework

• Order stats remote + models + tests
• Site visits remote + models + tests

Storage Framework

Order stats storage logic + tests (moved to #258)
Site visits storage logic + tests (moved to #258)

Yosemite Framework

• Order stats store + actions + tests
• Visit stats store + actions + tests

Main App

• Integrate with charting lib
• Create the corresponding view models for order stats and visits
• Scrollable segmented control component for card header
• Create Days, Weeks, Months, Years chart views
• Chart style
• Create textual "counts" view — "Visitors", "Orders", and "Revenue"
• Create last updated chart footer view — e.g. "Updated moments ago."
• Pull to refresh logic

Refs

Moved the remaining storage + entity listener work to their own issue (#258). Closing this! 🎉
