编辑：可视化现在可以工作，但只能使用这个小数据集。使用我的原始数据集（其大小至少是下面发布的数据集的十倍），可视化中不会显示任何内容。
我一直试图像这样制作堆积条形图：http://bl.ocks.org/mbostock/3886208但是使用json代替。出于某种原因，酒吧不会出现。除了变量名称更改之外，JS代码与示例代码完全相同：
var margin = {top: 20, right: 20, bottom: 20, left: 40},
width = 1000 - margin.left - margin.right,
height = 600 - margin.top - margin.bottom;
var x = d3.scale.ordinal()
.rangeRoundBands([0, width], .1);
var y = d3.scale.linear()
.rangeRound([height, 0]);
var color = d3.scale.ordinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left")
.tickFormat(d3.format(".2s"));
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 + ")");
d3.json ("stats_reformat_short.json", function (error, data) {
color.domain(d3.keys(data[0]).filter(function(key) { return key !== "Time"; }));
data.forEach(function(d) {
var y0 = 0;
d.concent = color.domain().map(function(name) { return {name: name, y0: y0, y1: y0 += +d[name]}; });
d.total = d.concent[d.concent.length - 1].y1;
});
x.domain(data.map(function(d) { return d.Time; }));
y.domain([0, d3.max(data, function(d) { return d.total; })]);
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
svg.append("g")
.attr("class", "y axis")
.call(yAxis)
.append("text")
.attr("transform", "rotate(-90)")
.attr("y", 6)
.attr("dy", ".71em")
.style("text-anchor", "end")
.text("Concentration");
var time = svg.selectAll(".time")
.data(data)
.enter().append("g")
.attr("class", "g")
.attr("transform", function(d) { return "translate(" + x(d.Time) + ",0)"; });
time.selectAll("rect")
.data(function(d) { return d.concent; })
.enter().append("rect")
.attr("width", x.rangeBand())
.attr("y", function(d) { return y(d.y1); })
.attr("height", function(d) { return y(d.y0) - y(d.y1); })
.style("fill", function(d) { return color(d.name); });
var legend = svg.selectAll(".legend")
.data(color.domain().slice().reverse())
.enter().append("g")
.attr("class", "legend")
.attr("transform", function(d, i) { return "translate(0," + i * 20 + ")"; });
legend.append("rect")
.attr("x", width - 18)
.attr("width", 0.1)
.attr("height", 0.1)
.style("fill", color);
legend.append("text")
.attr("x", width - 24)
.attr("y", 9)
.attr("dy", ".15em")
.style("text-anchor", "end")
.text(function(d) { return d; });
});
