             });
            },

            destroyed() {
             window.removeEventListener('resize', () => {});
            },


       //配置相
        getOption（）{

             this.chart = this.$echarts.init(this.$refs.echartRef);
             // 获取配置
             let option = this.getOption();
             // 绘制图表
             this.chart.setOption({ ...option });
             setTimeout(() => {
              window.addEventListener('resize', () => {
               this.chart && this.chart.resize();
              });
              this.chart && this.chart.resize();
