javascript – Chart.js删除堆叠

我有一个堆积条形图和两个折线图.第二个折线图堆叠在第一个折线图的顶部,但我不想要这种行为.

我试过的是显式设置堆栈模式为false,但是这个选项没有被执行.

            ...
            type: 'line',
            label: 'lineChart1',
            data: lineData1,
            borderWidth: 1,
            fill: false,
            options: {
              legend: {
                display: false
              },
              scales: {
                    xAxes: [{
                        stacked: false,
                    }],
                    yAxes: [{
                        stacked: false
                    }]
                }
            }
        }
        ...

解决方法:

下面是一个配置带有2个堆叠条和2个未堆叠线的图表的示例.我认为您在折线图上堆叠的原因是因为您没有在条形图中设置堆叠选项以给它们一个堆栈ID.

var myChart = new Chart(ctx, {
  type: 'bar',
  data: {
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [{
      type: 'line',
      label: 'Dataset 1',
      borderColor: window.chartColors.green,
      borderWidth: 2,
      fill: false,
      data: [5, 3, 4, 10, 8, 9, 2]
    }, {
      type: 'line',
      label: 'Dataset 2',
      borderColor: window.chartColors.orange,
      borderWidth: 2,
      fill: false,
      data: [8, 5, 2, 8, 7, 2, 6]
    }, {
      type: 'bar',
      label: 'Dataset 3',
      backgroundColor: window.chartColors.red,
      stack: 'Stack 0',
      data: [2, 4, 1, 3, 7, 3, 6],
      borderColor: 'white',
      borderWidth: 2
    }, {
      type: 'bar',
      label: 'Dataset 4',
      backgroundColor: window.chartColors.blue,
      stack: 'Stack 0',
      data: [7, 2, 4, 5, 6, 4, 2]
    }]
  },
  options: {
    responsive: true,
    title: {
      display: true,
      text: 'Chart.js Stacked Bar and Unstacked Line Combo Chart'
    },
    tooltips: {
      mode: 'index',
      intersect: true
    },
    scales: {
      xAxes: [{
        stacked: true,
      }]
    }
  }
});

这是一个codepen example,显示它的样子.
