Highcharts 向下钻取保证金

Question

不幸的是，向上钻取按钮通常位于图表顶部。我想将 marginTop 应用于向下钻取图，以便该图始终位于按钮下方。我用过这个example。如您所见，该按钮位于柱形图的顶部。 HTML

<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/drilldown.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

JavaScript

$(function() {

// Create the chart
$('#container').highcharts({
chart: {
  type: 'column',
  events: {
    drilldown: function(e) {
      if (!e.seriesOptions) {
        var drilldowns = {
          'animals': {
            name: 'Cats',
            color: '#fa7921',
            drilldown: 'Cats',
            data: [
              ['2014', 10],
              ['2015', 10],
              ['2016', 15],
            ]
          }
        },
            drilldowns2 = {
              'animals': {
                name: 'Cows',
                color: '#9bc53d',
                data: [
                  ['2014', 13],
                  ['2015', 15],
                  ['2016', 15]
                ]
              }
            },
            drilldowns3 = {
              'animals': {
                name: 'Sheep',
                color: '#e55934',
                data: [
                  ['2014', 13],
                  ['2015', 15],
                  ['2016', 15]
                ]
              }
            };

        this.addSingleSeriesAsDrilldown(e.point, drilldowns[e.point.name]);
        this.addSingleSeriesAsDrilldown(e.point, drilldowns2[e.point.name]);
        this.addSingleSeriesAsDrilldown(e.point, drilldowns3[e.point.name]);
        this.applyDrilldown();
      }
    }
  }
},
title: {
  text: 'Async drilldown'
},
xAxis: {
  type: 'category'
},

legend: {
  enabled: false
},

plotOptions: {
  series: {
    stacking: 'normal',
    borderWidth: 0,
    dataLabels: {
      enabled: true
    }
  }
},

series: [{
  name: 'Cats',
  color: '#fa7921',
  data: [{
    name: 'animals',
    y: 5,
    drilldown: true
  }]
}, {
  name: 'Cows',
  color: '#9bc53d',
  data: [{
    name: 'animals',
    y: 5,
    drilldown: true
  }]
}, {
  name: 'Sheep',
  color: '#e55934',
  data: [{
    name: 'animals',
    y: 5,
    drilldown: true
  }]
}],

drilldown: {
  series: []
}
});
});

希望有人知道一个简单的解决方案。

Answer 1

在drilldown 事件中更新图表的marginTop：

        this.update({
          chart: {
            marginTop: 50
          }
        }, false);

并在drillup事件中恢复它：

      this.update({
        chart: {
          marginTop: 10
        }
      }, false);

注意update() 的第二个参数是false - 这里不需要重绘图表。

查看drilldown.drillUpButton 文档

更新你的drilldown

   drilldown: {
      drillUpButton: {
        relativeTo: 'spacingBox',
        position: {
          y: 0,
          x: 0
        }
      },
      series: []
    }
