},
// 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)'
}
}
}
