my own d3 custom color scale - interpolate a range from one given HEX to another
0
I cannot create a custom color scale. I want d3 to interpolate a range from one hex to another
const colorRange = ['#d7191c', '#d55045']
const data = [617, 631, 640, 650]
const color = d3
.scaleLinear()
.domain(1, data.length)
.interpolate(d3.interpolateHcl)
.range([d3.hcl(colorRange[1]), d3.hcl(colorRange[0])])
console.log(color(1)) // returns 'rgb(0,0,0)' but expected some hex from the gradient from '#d55045' to '#d7191c'

You need to specify the domain correctly
const colorRange = ['#d7191c', '#d55045']
const data = [617, 631, 640, 650]
const color = d3.scaleLinear()
.domain([1, data.length])
.interpolate(d3.interpolateHcl)
.range([d3.hcl(colorRange[1]), d3.hcl(colorRange[0])])
console.log(color(1));<script src="https://d3js.org/d3.v5.min.js"></script>answered Nov 15 '18 at 12:13
