d3.js - D3js-Get the first and the last decile

Question

I have some data in a csv. I want to get the first and the last decile of all the numbers. I think I might need to use d3.scale.quantize() but I do not know how...

Thanks for your help I'm stuck since a while.

Answer 1

你可以使用d3.quantile()这个，即

d3.quantile(numbers, 0.1);
d3.quantile(numbers, 0.9);

演示在这里。
