堆积条形图：按类型和数量

时间：2018-11-07 08:19:32

标签： javascript dc.js crossfilter

我要使用Dc.Js和交叉过滤器来创建堆积条形图。

基本，我有两个变量：

类型：2018年，从不涵盖，其他期间

地区：Thu Duc等...

在我的StackedBarChart中，我想查看每个区域的数量。

我尝试使用此代码：

var paymentsRecord = [{
    date: "2011-11-14T16:17:54Z",
    quantity: 2,
    total: 190,
    tip: 100,
    type: "tab"
  },
  {
    date: "2011-11-14T16:20:19Z",
    quantity: 2,
    total: 190,
    tip: 100,
    type: "tab"
  },
  {
    date: "2011-11-14T16:28:54Z",
    quantity: 1,
    total: 300,
    tip: 200,
    type: "visa"
  },
  {
    date: "2011-11-14T16:30:43Z",
    quantity: 2,
    total: 90,
    tip: 0,
    type: "tab"
  },
  {
    date: "2011-11-14T16:48:46Z",
    quantity: 2,
    total: 90,
    tip: 0,
    type: "tab"
  },
  {
    date: "2011-11-14T16:53:41Z",
    quantity: 3,
    total: 90,
    tip: 0,
    type: "tab"
  },
  {
    date: "2011-11-14T16:54:06Z",
    quantity: 1,
    total: 100,
    tip: 0,
    type: "cash"
  },
  {
    date: "2011-11-14T16:58:03Z",
    quantity: 2,
    total: 90,
    tip: 0,
    type: "tab"
  },
  {
    date: "2011-11-14T17:07:21Z",
    quantity: 2,
    total: 90,
    tip: 0,
    type: "tab"
  },
  {
    date: "2011-11-14T17:22:59Z",
    quantity: 2,
    total: 90,
    tip: 0,
    type: "tab"
  },
  {
    date: "2011-11-14T17:25:45Z",
    quantity: 2,
    total: 200,
    tip: 0,
    type: "cash"
  },
  {
    date: "2011-11-14T17:29:52Z",
    quantity: 1,
    total: 200,
    tip: 100,
    type: "visa"
  }
];

var facts = crossfilter(paymentsRecord);
var dimensionByType = facts.dimension(function(d) {
  return d.type;
});
var groupByType = dimensionByType.group().reduce(reduceAdd, reduceRemove, reduceInitial);


function reduceAdd(p, v) {
  p[v.quantity] = (p[v.quantity] || 0) + v.total;
  return p;
}

function reduceRemove(p, v) {
  p[v.quantity] = (p[v.quantity] || 0) - v.total;
  return p;
}

function reduceInitial() {
  return {};
}

var barChart = dc.barChart("#stackedBarChart")
  .width(1024)
  .height(200)
  .dimension(dimensionByType)
  .group(groupByType, "Quantity: 1", function(d) {
    return d.value[1] || 0;
  })
  .stack(groupByType, "Quantity: 2", function(d) {
    return d.value[2];
  })
  .stack(groupByType, "Quantity: 3", function(d) {
    return d.value[3];
  })
  .x(d3.scale.ordinal().domain(['tab', 'visa', 'cash']))
  .xUnits(dc.units.ordinal)
  .legend(dc.legend().x(500).y(1).itemHeight(15).gap(5));
barChart.yAxis().ticks(5);
barChart.xAxis().ticks(4);


dc.renderAll();

我该如何满足我的需求？

1 个答案:

答案 0 :(得分：2)

您必须这样设置x比例尺（即使您使用.elasticX(true)）：

.x(d3.scale.ordinal())

还要注意，在.group和.stack回调中，您必须使用与reduceAdd和reduceRemove中使用的名称相同的名称（type属性）。
由于您的数据集缺少total属性和类似值的任何内容，因此我选择在以下演示中显示latitude：
