Fixes for vega time series views ...

[rufuspollock]

@zelima to fill this in ...

Suggest you work on this even in a separate small repo with some data and some vega views hand constructed ...

@rgrp I've opened new repo separately: https://github.com/zelima/graph-views
For now:

• graph works with different time series (Annual, Monthly, Daily). Using JS switch statement
• shows correct Y-Axis value (Price) on hover.
• shows correct X-Axis value (Date) on hover.
  • Does not show 0 before months and dates that are <10 Should support YYYY-MM-DD date formatting zelima/graph-views#1

@zelima ok - you can have elsewhere but i would like a checklist here still of all the issues you told me about last week (and I can't see those in graph-views either). IIRC you had at least 4 or so (e.g. loads of digits in decimals etc etc).

• Graph shows correct time period on hover, formatted YYYY-MM-DD, YYYY-MM, or YYYY as needed
  • Formatted time shows 0 before numbers less then 10
