work in progress

calculate some sensible break-points between two numbers

npm i somehow-ticks

const somehowTicks = require('somehow-ticks')

let ticks = somehowTicks(0, 5000, 5)
/*
[ { label: '1k', number: 1000, value: 0.2 },
  { label: '2k', number: 2000, value: 0.4 },
  { label: '3k', number: 3000, value: 0.6 },
  { label: '4k', number: 4000, value: 0.8 } ]
*/

This library has some opinions:

• ticks should always be spaced evenly, even if this means less ticks
• a tick should appear x.0 or x.5
• they don't need to begin or end at the start and end.
• less ticks are better than too-many ticks

it was built for labelling an x-axis in a space-limited way, but you can use it for whatever weird stuff.
