chartDialog1() { this.chartVisiable1 = !this.chartVisiable1; this.$nextTick(()=>{ var zongjineChart1 = echarts.init(document.getElementById("zongjineChart1"),'macarons'); this.$http({ url: `jingdiangoupiao/value/jingdianmingcheng/zongjine`, method: "get", }).then(({ data }) => { if (data && data.code === 0) { let res = data.data; let xAxis = []; let yAxis = []; let pArray = [] for(let i=0;i<res.length;i++){ xAxis.push(res[i].jingdianmingcheng); yAxis.push(parseFloat((res[i].total))); pArray.push({ value: parseFloat((res[i].total)), name: res[i].jingdianmingcheng }) } var option = {};

这是一个使用 Echarts 库进行图表绘制的函数，当调用该函数时，会根据传入的参数显示或隐藏图表。函数内部使用了 Vue.js 中的 $http 方法向后端发送请求获取数据，然后将数据处理成适合 Echarts 绘制的格式，并根据数据绘制出对应的图表。具体的图表类型和样式可以参考函数中的 option 对象。

相关问题

this.chartVisiable1 = !this.chartVisiable1; this.$nextTick(()=>{ var zongjineChart1 = echarts.init(document.getElementById("zongjineChart1"),'macarons');

这是一段 JavaScript 代码，它的作用是切换图表的可见性，并使用 ECharts 库初始化一个名为 zongjineChart1 的图表。其中，`this.chartVisiable1` 是一个变量，用于记录图表的可见性状态，`!this.chartVisiable1` 则表示将其状态取反。`this.$nextTick()` 是 Vue.js 框架提供的方法，用于在 DOM 更新后执行回调函数，这里的回调函数用于初始化图表。具体实现可以参考 ECharts 文档和 Vue.js 文档。

data() { return { flag: false, flag1: false, flag2: false, flag3: false, flag4: false, flag5: false, }; }, components: { hot, seller, trend, Map, rank, stock, }, methods: { changetheme() { this.$store.commit("tabtheme"); }, full() { this.flag = true; this.$nextTick(() => { this.$refs.seller2.changesize(); }); }, full1() { this.flag1 = true; this.$nextTick(() => { this.$refs.trend2.screenAdapter(); }); }, full2() { this.flag2 = true; this.$nextTick(() => { this.$refs.rank2.screenAdapter(); }); }, full3() { this.flag3 = true; this.$nextTick(() => { this.$refs.hot2.screenAdapter(); }); }, full4() { this.flag4 = true; this.$nextTick(() => { this.$refs.stock2.screenAdapter(); }); }, full5() { this.flag5 = true; this.$nextTick(() => { this.$refs.map2.screenAdapter(); }); },优化后代码

data() {
return {
flags: [false, false, false, false, false, false],
};
},
components: {
hot,
seller,
trend,
Map,
rank,
stock,
