d3.js:直方图不呈现，如果域不是以0开始(表示[0，*])

我是d3.js的新手，问自己为什么下面的直方图不呈现。它基于http://bl.ocks.org/mbostock/3048450的简单直方图演示，其中唯一显著的区别是x尺度的域:它不是从0开始，而是从10开始。更改范围可以使其工作。

• http://jsfiddle.net/7J9GN/1/domain = [10, 100]不工作
• //jsfiddle.net/7J9GN/2/domain = [0, 100] - working

var numOfBins = 10;
var values = [10, 55, 60, 90, 95];
// A formatter for counts.
var formatCount = d3.format(",.0f");
var margin = {top: 10, right: 30, bottom: 30, left: 30},
    width = 960 - margin.left - margin.right,
    height = 500 - margin.top - margin.bottom;
var x = d3.scale.linear()
    .domain([
        Math.floor(d3.min(values) / numOfBins) * numOfBins, // 10
        Math.ceil(d3.max(values) / numOfBins) * numOfBins // 100
    ])
    .range([0, width]);
// Generate a histogram using numOfBins uniformly-spaced bins.
var data = d3.layout.histogram()
    .bins(x.ticks(numOfBins))
    (values);
var y = d3.scale.linear()
    .domain([0, d3.max(data, function(d) { return d.y; })])
    .range([height, 0]);
var xAxis = d3.svg.axis()
    .scale(x)
    .orient("bottom");
var svg = d3.select("body").append("svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
  .append("g")
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")");
var bar = svg.selectAll(".bar")
    .data(data)
  .enter().append("g")
    .attr("class", "bar")
    .attr("transform", function(d) { return "translate(" + x(d.x) + "," + y(d.y) + ")"; });
bar.append("rect")
    .attr("x", 1)
    .attr("width", x(data[0].dx) - 1)
    .attr("height", function(d) { return height - y(d.y); });
bar.append("text")
    .attr("dy", ".75em")
    .attr("y", 6)
    .attr("x", x(data[0].dx) / 2)
    .attr("text-anchor", "middle")
    .text(function(d) { return formatCount(d.y); });
svg.append("g")
    .attr("class", "x axis")
    .attr("transform", "translate(0," + height + ")")
    .call(xAxis);
