Question

我用高图js库制作了一个向下钻取条形图，其中列具有不同的间隔。因为我想制作不同大小的条形图，所以我使用了加载和渲染功能来改变条形图的大小。

现在我想知道如何使xAxis标签与每个条的当前位置相匹配。而且我的工具提示和数据标签与xAxis标签有同样的问题，我想知道如何解决这个问题？

// Create the chart
Highcharts.chart('container', {
  chart: {
    type: 'column',
    events: {
      load: function() {

        this.series[0].data[0].graphic.attr({
          x: 10,
          width: 20
        });
        this.series[0].data[1].graphic.attr({
          x: 80,
          width: 40
        });
        this.series[0].data[2].graphic.attr({
          x: 150,
          width: 80
        });
      },
      render: function() {
        console.log(this.series[0].options._levelNumber)
        if (this.series[0].options._levelNumber == 0) {
          this.series[0].data[0].graphic.attr({
            x: 10,
            width: 20
          });
          this.series[0].data[1].graphic.attr({
            x: 80,
            width: 40
          });
          this.series[0].data[2].graphic.attr({
            x: 150,
            width: 80
          });
        }
      }
    }
  },
  title: {
    text: 'Basic drilldown'
  },
  xAxis: {
    type: 'category',
    title: {
      enabled: true,
      text: "Percentage Range"
    }
  },
  yAix: {
    title: {
      enabled: true,
      text: "Number of Schools"
    }
  },

    enabled: false

  plotOptions: {
    series: {
      borderWidth: 0,
      dataLabels: {
        enabled: true
      }
    }
  },

  series: [{
    name: 'Things',
    colorByPoint: true,
    data: [{
      name: '100-70%',
      y: 5,
      drilldown: '100-70%'
    }, {
      name: '70-30%',
      y: 2,
      drilldown: '70-30%'
    }, {
      name: '30-0%',
      y: 4,
      drilldown: '30-0%'
    }]
  }],
  drilldown: {
    series: [{
      id: '100-70%',
      data: [
        ['Cats', 4],
        ['Dogs', 2],
        ['Cows', 1],
        ['Sheep', 2],
        ['Pigs', 1]
      ]
    }, {
      id: '70-30%',
      data: [
        ['Apples', 4],
        ['Oranges', 2]
      ]
    }, {
      id: '30-0%',
      data: [
        ['Toyota', 4],
        ['Opel', 2],
        ['Volkswagen', 2]
      ]
    }]
  }

您可以使用pointPadding或pointWidth来定义每个数据系列，而不是使用事件来更改列的宽度。这会正确显示图表

系列将是

  series: [{
    name: 'Things',
    colorByPoint: true,
    pointPadding: 0,
   // pointWidth:80, you can use this as well
    data: [{
      name: '100-70%',
      y: 5,
      drilldown: '100-70%',
    }]
  }, {
    name: 'Things',
    colorByPoint: true,
    pointPadding: 0.2,
    // pointWidth:100, you can use this as well
    data: [{
      name: '70-30%',
      y: 2,
      drilldown: '70-30%'
    }]
  }, {
    name: 'Things',
    colorByPoint: true,
    pointPadding: 0.3,
    // pointWidth:120, you can use this as well
    data: [{
      name: '30-0%',
      y: 4,
      drilldown: '30-0%'
    }]
  }],
