Question

我只是想在我的'柱形图'上禁用DRILL-DOWN效果。有人可以帮忙吗？以下是Fiddle http://jsfiddle.net/D8Ez3/

的示例代码

*如您所见，图表的图例是可点击的。我需要图例中的项目不可点击，因为当您单击所有项目时，图表将返回空白。我宁愿不对图表进行深入研究。有什么想法吗？

chart = new Highcharts.Chart({
    chart: {
        renderTo: 'impact',
        type: 'column',
        margin: [0, 0, 0, 0],
        spacingTop: 0,
        spacingBottom: 0,
        spacingLeft: 0,
        spacingRight: 0,
        backgroundColor: null,
        events: {
            load: function (event) {
                console.log(this);
            }}},
    exporting: {
       buttons: { 
       exportButton: {
       enabled:false
    },
    printButton: {
        enabled:false
    }}},
credits: {
        enabled: false
    },
    title: {
        text: ''
    },
    subtitle: {
        text: ''
    },
    xAxis: {
        categories: ['Reporting Year']
    },
    yAxis: {
        min: 0,
        title: {
            text: 'Millions (mm)'
        }
    },
    legend: {
    enabled:false,
        layout: 'vertical',
        backgroundColor: '#FFFFFF',
        align: 'left',
        verticalAlign: 'top',
        x: 50,
        y: 30,
        floating: true,
        shadow: true
    },
    tooltip: {
        formatter: function () {
            return '' + this.x + ': ' + this.y + ' mm';
        }
    },
    plotOptions: {
        column: {
            pointPadding: 0.2,
            size: '95%',
            borderWidth: 0},
    point: {
                events: {
                    legendItemClick: function () {
                        return true; // <== returning false will cancel the
                        default action }}},
            allowPointSelect: false,
    },
    series: [{
        name: 'Yr 1',
        data: [23.7] }, 
    {
        name: 'Yr 2',
        data: [13.6] }, 
    {
        name: 'Yr 3',
        data: [49.9] }, 
    {
        name: 'Yr 4',
        data: [83.6] }]
      });

Answer 1

你很亲密。而不是：

plotOptions: {
    column: {
        pointPadding: 0.2,
        size: '95%',
        borderWidth: 0
    },
    point: {
            events: {
                legendItemClick: function () {
                    return false; // <== returning false will cancel the default action
                }
            }
    },
    allowPointSelect: false,
},

你想：

plotOptions: {
    column: {
        pointPadding: 0.2,
        size: '95%',
        borderWidth: 0,
        events: {
            legendItemClick: function () {
                return false; 
            }
        }
    },
    allowPointSelect: false,
},

Answer 2

如果你使用馅饼，你必须这样做：

    pie: {
       showInLegend: true,
       allowPointSelect: false,
       point:{
           events : {
            legendItemClick: function(e){
                e.preventDefault();
            }
           }
       }
   }

Answer 3

This is the way to make legends of Highcharts graph non-clickable because whenever you click on a particular legend than corresponding slice become disappear from graph so make graph persist as per business requirement we may make legends unclickable.

  plotOptions: {
        column: {
            pointPadding: 0,
            borderWidth: 1,
        },
        series: {
            events: {
                legendItemClick: function (e) {
                    e.preventDefault();
                }
            }
        }
    }

Answer 4

以下是JSFiddle演示如何实现此目标：

plotOptions: {
        series: {
            events: {
                legendItemClick: function () {
                    var visibility = this.visible ? 'visible' : 'hidden';
                    if (!confirm('The series is currently ' +
                   **strong text**              visibility + '. Do you want to change that?')) {
                        return false;
                    }
                }
            }
        }
    }

Answer 5

如果使用 ES6 ，则可以通过箭头功能使其更短，因为它指向 DOM元素，您只需返回 false 。 ..

{
  name: 'Name of this chart',
  type: 'line',
  lineWidth: 1,
  color: '#333333',
  events: {
    legendItemClick: () => false  // disable legend click
  },
  data: [1, 5, 10, 8, 19, 28, 0 , 12]
};

Answer 6

来自Highcharts JS API documentation（v7.1.1）

”默认操作是切换点的可见性。这可以可以通过调用event.preventDefault（）来阻止。”

这对饼图来说对我有用-

    plotOptions: {
        pie: {
            point: {
                events: {
                    legendItemClick: function (e) {
                        e.preventDefault();
                    }
                }
            }
        }
    }

Answer 7

作为对其他答案的有用补充，您可能还希望禁用图例悬停样式：

legend: {
    itemStyle: {
        cursor: 'default',
    },
    itemHoverStyle: {
        color: '#333333',
    }
},
