javascript - Highchart Js 中的工具提示修改

Question

我正在修改图表中Highchart JS的工具提示。但产出并没有像我预期的那样。我想在工具提示的右侧打印百分比。

示例:满意到忠诚:4 (20%)

我添加了两个数组，根据一系列图表在工具提示右侧添加 valueSuffix。但它在单个工具提示上打印所有数组值。

我尝试了下面的代码来修改 Highchart。

$(function() {
  $('#container').highcharts({
    title: {
      text: ''
    },
    charts: {
      zoomType: 'xy',
    },
    exporting: {
      enabled: false
    },
    xAxis: {
      categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
        'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
      ],
    },
    yAxis: {
      title: '',
    },
    labels: {
      items: [{
        style: {
          left: '50px',
          top: '18px',
        }
      }]
    },
    tooltip: {
      shared: true,
    },
    credits: {
      enabled: false
    },
    plotOptions: {
      series: {
        label: {
          enabled: false
        },
      },
      column: {
        states: {
          hover: {
            color: '#90D0FF'
          }
        }
      }
    },
    series: [{
        type: 'column',
        name: 'Provide Feedback',
        data: [10, 4, 5, 6, 8, 9, 2, 3, 4, 5, 6, 9],
        color: 'yellow'
      },
      {
        name: 'Satisfied to Loyal',
        type: 'spline',
        data: [2, 5, 4, 3, 2, 3, 7, 8, 9, 5, 4, 3],
        color: '#55BF3B',
        dataLabels: {
          enabled: false
        },
        tooltip: {
          valueSuffix: [' (1%)', ' (2%)', ' (18%)', ' (10%)', ' (3%)', ' (1%)', ' (1%)', ' (6%)', ' (4%)', ' (1%)', ' (8%)', ' (70%)'],
          // valueSuffix: ' (val %)',
        },
        marker: {
          lineWidth: 4,
          fillColor: 'white',
          width: 16,
          height: 16
        }
      },
      {
        name: 'Unhappy to Satisfied',
        type: 'spline',
        data: [1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 5, 4],
        color: '#FFC800',
        tooltip: {
          valueSuffix: [' (10%)', ' (12%)', ' (1%)', ' (100%)', ' (30%)', ' (10%)', ' (10%)', ' (60%)', ' (34%)', ' (10%)', ' (98%)', ' (40%)'],
          // valueSuffix: ' (val %)',
        },
        marker: {
          lineWidth: 4,
          fillColor: 'white',
          width: 16,
          height: 16
        }
      }
    ]
  });
});

非常感谢任何帮助。

您可以在pointFormatter函数中从图表之外的数组中获取后缀:

var valueSuffix1 = [' (1%)', ' (2%)', ' (18%)', ' (10%)', ' (3%)', ' (1%)', ' (1%)', ' (6%)', ' (4%)', ' (1%)', ' (8%)', ' (70%)'];

var valueSuffix2 = [' (10%)', ' (12%)', ' (1%)', ' (100%)', ' (30%)', ' (10%)', ' (10%)', ' (60%)', ' (34%)', ' (10%)', ' (98%)', ' (40%)'];

$('#container').highcharts({

    ...

    tooltip: {
        shared: true,
        pointFormatter: function() {
            var suffix = '';

            if (this.series.index === 1) {
                suffix = valueSuffix1[this.index]
            } else if (this.series.index === 2) {
                suffix = valueSuffix2[this.index]
            }

            return '<span style="color:' + this.color + '">\u25CF</span> ' + this.series.name + ': <b>' + this.y + '</b>' + suffix + '<br/>'
        }
    }
});
