Vue-echarts：工具提示适用于除我的一张图表之外的所有图表。为什么？

Question

我开发的一个应用中有几个echarts。我正在使用 echarts 的 V4（目前还不能升级）并按照此处找到的工具提示使用文档进行操作：https://echarts.apache.org/v4/en/option.html#tooltip 除了我最新的以外，所有工具提示都显示得很好。我看不出新的和旧的有什么区别。

我已经明确地导入了正确的模块，如这个问题的答案中所述：Apache ECharts with Vue does not show Tooltip 就像我为我的旧模块所做的那样。

我用的是vue文件，上面是模板，中间是脚本，下面是css。该图表在模板中定义如下：

<echarts
  id="alertPie"
  :options="option"
  class="alertChart"
  autoresize
/>

在我的脚本部分，我有这些导入：

import 'echarts/lib/chart/pie'
import 'echarts/lib/component/tooltip'
import 'echarts/lib/component/title'
import 'echarts/lib/component/legend'

图表的“选项”是这样定义的计算字段：

computed: {
    option () {
      return {
        backgroundColor: '#efefef',
        textStyle: {
          fontStyle: 'italic',
          fontWeight: 'bold'
        },
        title: {
          text: 'Alert Adoption',
          subtext: 'Count by Alert',
          left: 'center',
          top: 10,
          textStyle: {
            color: '#ee0022',
            textBorderColor: '#000000',
            textBorderWidth: 2,
            textShadowColor: 'rgba(0,0,0,0.5)',
            textShadowBlur: 4,
            fontWeight: 'bold',
            textShadowOffsetX: 2,
            textShadowOffsetY: 2,
            fontSize: 28
          },
          subtextStyle: {
            color: 'black'
          }
        },
        tooltip: {
          trigger: 'item',
          formatter: '{a} <br/>{b} : {c} ({d}%)'
        },
        legend: {
          // orient: 'vertical',
          // top: 'middle',
          bottom: 10,
          left: 'center'
        },
        series: [
          {
            name: 'pie',
            type: 'pie',
            data: this.alertPieData,
            radius: '40%',
            center: ['50%', '40%'],
            selectedMode: 'single',
            itemStyle: {
              emphasis: {
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: 'rgba(0, 0, 0, 0.5)'
              }
            }
          }
        ],
        animationDuration: 2000
      }
    }
  }

饼图正确显示了数据。标题和图例均正确显示。在导入的项目中，只有工具提示不起作用。

就像我说的，我的其他图表构建相同，工具提示也有效。我错过了什么？我盯着这个看，并与我的工作示例进行了比较，没有发现任何差异（除了数据源和 title/label 更改）。

有什么想法吗？

数据示例如下：

[ { "name": "Acthar Gel Med Order Alert", "value": 10 }, 
{ "name": "Anticoagulation / Hemoglobin Alert", "value": 6 }, 
{ "name": "Anticoagulation or Dual Antiplatelet / Hemoglobin Alert", "value": 7 }, 
{ "name": "Berinert Alert", "value": 10 }, 
{ "name": "Blood Culture Identification Alert", "value": 13 }, 
{ "name": "Clostridium Difficile Alert", "value": 9 }, 
{ "name": "Clostridium Difficile Lab Order Alert", "value": 15 }, 
{ "name": "Controlled Substance - Pyxis Removal / Late Admin Alert", "value": 13 } ]

我已经用 CDN 试过了，应该可以。
