</template>

<script>
import echarts from 'echarts'
import 'echarts/theme/macarons.js'

export default {
  name: 'EchartsPieChart',
  mounted() {
    this.initEchartsPieChart()
  },
  methods: {
    initEchartsPieChart() {
      const echartsPieChart = echarts.init(this.$refs.echartsPieChart, 'macarons')
      const option = {
        title: {
          text: 'Echarts Pie Chart',
          subtext: 'By Vue.js'
        },
        tooltip: {
          trigger: 'item',
          formatter: '{a} <br/> {b}: {c} ({d}%)'
        },
        legend: {
          orient: 'vertical',
          left: 10,
          data: ['A', 'B', 'C', 'D', 'E']
        },
        series: [
          {
            name: 'Echarts Pie Chart',
            type: 'pie',
            radius: ['50%', '70%'],
            avoidLabelOverlap: false,
            label: {
              show: false,
              position: 'center'
            },
            emphasis: {
              label: {
                show: true,
                fontSize: '30',
                fontWeight: 'bold'
              }
            },
            labelLine: {
              show: false
            },
            data: [
              { value: 335, name: 'A' },
              { value: 310, name: 'B' },
              { value: 234, name: 'C' },
              { value: 135, name: 'D' },
              { value: 548, name: 'E' }
            ]
          }
        ]
      }
      echartsPieChart.setOption(option)
    }
  }
}
</script>

<style scoped>
.echarts-pie-chart {
  margin: 0 auto;
