  </div>
</template>

<script>
import * as echarts from 'echarts';
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  },
  mounted () {
    var myChart = echarts.init(document.getElementById('mychart'));
    // 绘制图表
    myChart.setOption({
         tooltip: {
        trigger: 'item',
        formatter: "{a} <br/>{b}: {c} ({d}%)"
    },
    legend: {
        orient: 'vertical',
        x: 'left',
        data:['直接访问','邮件营销','联盟广告','视频广告','搜索引擎']
    },
    series: [

            type:'pie',
            radius: ['50%', '70%'],
            avoidLabelOverlap: false,
            label: {
                normal: {

                    position: 'center'
                },
