d3.js y轴最小和最大值范围显示

Question

I have data points from 5000 to 91200

y.domain(d3.extent(function(d) { return d.y; }));

It gives me the correct ouput [5000, 91200] but while displaying it changes to 10000.

Does anyone know how I can resolve this issue?

Answer 1

d3 uses the 'min' and 'max' functions to show only the lowest and highest numbers in your data

var max = d3.max(d3.values(data)); 
var min = d3.min(d3.values(data)); 
y.domain([min, max]);

The extent function actually does both of these functions automagically

y.domain(d3.extent(data, function(d) { return d; }));

If you show your code on jsfiddle I'll be able to narrow down your issue
