<template>
  <div id="progress_bar" ref="myChart"></div>
</template>

<script>
import * as echarts from 'echarts';

    }
  },
  data() {
    return {
      myChart: null,
      option: {}
    };
  },
  created() {
    this.resize = debounce(this.resize, 300);
  },
  mounted() {
    this.$nextTick(() => {
      this.initProgressBar();
    });
  },

                barBorderRadius: 9
              },
              zlevel: 1
            },
            {

                }
              }

　　　　　　　　//itemStyle: { ======================颜色不渐变=========               //图形样式                 //normal: {                   //normal 图形在默认状态下的样式;                   //emphasis图形在高亮状态下的样式                  // barBorderRadius: 10, //柱条圆角半径,单位px.                   //此处统一设置4个角的圆角大小;                   //也可以分开设置[10,10,10,10]顺时针左上、右上、右下、左下                 //  color: '#007980'                 //}               //},

            }
          ]
        };
        this.myChart.setOption(this.option, true);
    }
  },
  beforeDestroy() {
    removeListener(this.$refs.myChart, this.resize);
    this.myChart.dispose();
    this.myChart = null;
  }
};
</script>

<style lang="scss" scoped>
#progress_bar {
  width: 100%;
