Customization / clean up of units

[hoorayimhelping]

Background

There's currently limited ability to change the units on a graph. There are three choices (none, si, binary) with some prefix or suffix label options. We want to give users more control of the units.

Additional options

• Comma separation
  • if true separate every third character with a comma starting from the beginning of the string
  • Essentially turns 1000 into 1,000
• Unit scale & Suffix/Prefix scale
  • Different than y axis scale
  • User would specify an array of when to "scale" up the unit by entering comma separated values instead of a single value
  • For example, a time unit scale would be [0,60, 60, 24, 30]. You could match unit scale to suffix scale [s,m,h,d,mo]
  • Another example would be bits:
    • unit scale: [0, 1024, 1024, 1024, 1024]
    • suffix scale: [b, Kb, Mb, Gb, Tb]

Presets

• Once the above options are implemented we can also implement unit presets, which represent common combinations of options for specific units
• Example:
  • $USD
    • 2 decimal points
    • comma separation true
    • prefix with $
    • unit scale with [0,1000,1000,1000,1000]
    • suffix scale with [,,M,B,T] (first two are blank)
  • Bytes
    • 2 decimal points
    • unit scale with [0,1024,1024,1024,1024]
    • suffix scale with [b,Kb,Mb,Gb,Tb,Pb]

This issue is a proof of concept for some of these ideas in giraffe https://github.com/influxdata/giraffe/pull/580

If we want to see this work fully it will take more time than we are currently willing to dedicate to it.
