1.自定义  图表  组件

Echarts.vue

export default {

props: {

// 样式

echartStyle: {

type: Object,

default(){

return {}

}

},

// 标题文本

titleText: {

type: String,

default: ''

},

// 提示框键名

tooltipFormatter: {

type: String,

default: ''

},

// 扇形区域名称

opinion: {

type: Array,

default(){

return []

}

},

// 提示框标题

seriesName: {

type: String,

default: ''

},

// 扇形区域数据

opinionData: {

type: Array,

default(){

return []

}

},

},

data(){

return {

//

}

},

mounted(){

this.$nextTick(function() {

this.drawPie('myChart')

})

},

methods: {

// 监听扇形图点击

eConsole(param) {

// 向父组件传值

this.$emit("currentEchartData",param.name);

},

// 绘制饼状图

drawPie(id){

this.charts = this.$echarts.init(document.getElementById(id));

this.charts.on("click", this.eConsole);

this.charts.setOption({

title: {

text: this.titleText, // 标题文本

left: 'center'

},

tooltip : {

trigger: 'item',

formatter: "{a}
" + this.tooltipFormatter + ":{c}"

},

legend: {

bottom: 20,

left: 'center',

data: this.opinion // 扇形区域名称

},

series : [

{

name:this.seriesName, // 提示框标题

type: 'pie',

radius : '65%',

center: ['50%', '50%'],

selectedMode: 'single',

data:this.opinionData, // 扇形区域数据

itemStyle: {

emphasis: {

shadowBlur: 10,

shadowOffsetX: 0,

shadowColor: 'rgba(0, 0, 0, 0.5)'

}

}

}

]

})

}

}

}

#myChart{

width: 100%;

}

2.页面调用

Diagram.vue

import mEcharts from '../components/Echarts'

export default {

name: 'Diagram',

components: {

mEcharts

},

data(){

return {

a:'水果销售统计',

b:'销售数量',

c:['香蕉','苹果','橘子'],

d:'销售统计',

e:[

{value:3, name:'香蕉'},

{value:3, name:'苹果'},

{value:3, name:'橘子'}

],

s: {

height: ''

}

}

},

created(){

// 获取屏幕高度

this.s.height = document.documentElement.clientHeight - 44 + 'px';

},

methods: {

getEchartData(val){

console.log(val);

}

}

}

//
