// 饼图
let echart = echarts.init(document.getElementById(this.echartId.source));
echart.setOption({
series: [
{
type: 'pie',
data: [
{ value: 335, name: '教师', itemStyle: { color: '#204570' } },
{ value: 234, name: '学生', itemStyle: { color: '#204570' } },
{ value: 1548, name: '职工', itemStyle: { color: '#204570' } }
],
radius: ['30%', '50%'],

});
echart.dispatchAction({
