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.

You can use d3.quantile() for this, i.e.

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

Demo here.

Thanks, but how can I get `numbers` from csv ? `d.aValue` ? `function(d){return d.aValue;}` – Melki Jan 21 '14 at 21:57

That depends entirely on your application. – Lars Kotthoff Jan 22 '14 at 09:22
