calculate some sensible break-points between two dates, using the spacetime date library.
npm i spacetime-ticks
import spacetimeTicks from 'spacetime-ticks'
let ticks = spacetimeTicks('June 5th 1992', 'Oct 4 2002', 5)
// [
// { label: "1993", epoch: 725864400000, value: 0.055 }
// { label: "1995", epoch: 788936400000, value: 0.248 }
// { label: "1997", epoch: 852094800000, value: 0.442 }
// { label: "1999", epoch: 915166800000, value: 0.636 }
// { label: "2001", epoch: 978325200000, value: 0.829 }
// ]This library has some opinions:
- ticks should always be
spaced evenly, even if this means less ticks - a tick should appear at the start of months, years, days
- they don't need to begin or end at the start andend.
- 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.
