Question

我在使用上述版本创建和显示堆积条形图时遇到了一些麻烦。文档没有解释这个主题。

任何人都有一个有用的想法？

var data = {
    "labels": [
      "10/7/15", 
      "10/8/15", 
      "10/9/15", 
      "10/13/15", 
      "10/14/15", 
      "10/15/15", 
      "10/16/15"
    ],
    "datasets": [{
      "label": "Cash",
      "backgroundColor": "blue",
      "data": [
        "100000", 
        "150000", 
        "120000", 
        "140000", 
        "90000", 
        "110000", 
        "130000"
      ]
    }, {
      "label": "Credit",
      "backgroundColor": "green",
      "data": [
        "20000",
        "-10000",
        "200000",
        "-110000",
        "99500",
        "-100000",
        "11000"
      ]
    }]
  };

  var options = {
    responsive: true,
    datasetFill: false,
    scales: {
      xAxes: [{
        stacked: true,
        barPercentage: 0.8
      }]
    },
  };
  var ctx = $('#bar_chart').get(0).getContext('2d');
  var chart = new Chart(ctx, {
    type: 'bar',
    data: data,
    options: options
  });

http://nnnick.github.io/Chart.js/docs-v2/#bar-chart处的文档表明＆＃34;堆积：真＆＃34;应该在xAxes值上设置，这是我做的无效。

好的，明白了。看起来我需要堆叠：两个轴都是真的，X和Y.
