我正在尝试将饼图 Highchart 的标题文本居中对齐。能够实现这一点，但是当鼠标悬停和鼠标移出时，标题数据不会更新。任何人都可以帮助我。在 MouseHOver 上尝试执行下面提到的代码

 point: {
            events: {
              mouseOver: function() {
                                                  let span = '<span style="color:${this.color}" class="dealer-title">${this.y}<br/> <span style="color:#33383e;}" class="text-truncate" title="${this.name}"><b> </b></span></span>';

                $('.customTitle')[0].innerHTML = span
              }
            }
          }
        }
      },

您需要在text中启用usehtml参数方法调用：

  chart: {
    type: 'pie',
    events: {
      load: function() {
        ...
        var text = rend.text("textTexttext", left, top, true).attr({
            'text-anchor': 'middle',
            align: 'center',
            'zIndex': 10
          }).addClass('customTitle').add();
      }
    }
  }

You need to enable useHTML argument in the text method call:

  chart: {
    type: 'pie',
    events: {
      load: function() {
        ...
        var text = rend.text("textTexttext", left, top, true).attr({
            'text-anchor': 'middle',
            align: 'center',
            'zIndex': 10
          }).addClass('customTitle').add();
      }
    }
  }
