Expected behaviour [期望结果]

不报错

ECharts option [ECharts配置项]

var option = {
  graphic: {
    id: 'text1',
    type: 'rect',
    shape: {
      x:0,
      y:0,
      width: 100,
      height: 100,
    },
    style: {
      fill: 'red',
    }
  },
};

var myChart = echarts.init(document.getElementById('main'));
myChart.setOption(option);

window.onresize = function() {
  document.getElementById('wid').innerText = window.innerWidth;
  var option = myChart.getOption();
  if (window.innerWidth < 600) {
    option.graphic = { // 删除上例中定义的 'text1' 元素。
      id: 'text1',
      $action: 'remove'
    }
  }
  else {
    option.graphic = {
      id: 'text1',
      type: 'rect',
      shape: {
        x:0,
        y:0,
        width: 100,
        height: 100,
      },
      style: {
        fill: 'red',
      }
    }
  }
  myChart.setOption(option);
}

window.onresize();

你可以改用 window事件监听，或是，写一个js方法，通过监听 获取到的 width 的值，如果值大于 600，再去调echarts图表试一下。
