接口得到的数据如下

要经过排序 ，计算累计百分比得到数据

蓝色 柱状图数据： 取count字段值

横坐标：取 id值

折线图：根据柱状图的数据计算累计百分比

 getInterface(data) {getParetoChart(data).then((res) => {if (res) {this.xList = res.map(item => {return window.vm.$i18n.t(`MsgAlarmType.${item.id}`)});let data = res.map(item => {return item.count});// 对数据进行排序data.sort((a, b) => b - a);this.countList = data// 计算总和const total = data.reduce((sum, value) => sum + value, 0);// 计算累计百分比let cumulativePercentage = 0;this.percentList = data.map(value => {const percentage = (value / total) * 100;cumulativePercentage += percentage;return cumulativePercentage.toFixed(2);});}});},
