代码中存在一些问题，包括：

1. 第一行的数组声明不完整，应该在外层加上方括号，即：

const rawData = [
  ['Income', 'Name', 'Year', 'Country'],
  [127931.772548, '生产一班', 2011, 'abc'],
  [127931.772548, '生产一班', 2012, 'abc'],
  [127931.772548, '生产一班', 2013, 'abc'],
  [127931.772548, '生产一班', 2014, 'abc'],
  [127931.772548, '生产一班', 2015, 'abc'],
  [127931.772548, '生产一班', 2016, 'abc'],
  [127931.772548, '生产一班', 2017, 'abc'],
  [127931.772548, '生产一班', 2018, 'abc']
];

2. 变量 `_rawData` 未定义，应该改为 `rawData`。

3. `echarts.util.each()` 方法应该改为 `echarts.util.eachAxisDim()` 或 `echarts.util.eachAxis()` 方法。

4. 在 `seriesList` 中，`itemName` 应该改为 `name`。

修改后的代码如下：

const rawData = [
  ['Income', 'Name', 'Year', 'Country'], 
  [127931.772548, '生产一班', 2011, 'abc'], 
  [127931.772548, '生产一班', 2012, 'abc'], 
  [127931.772548, '生产一班', 2013, 'abc'], 
  [127931.772548, '生产一班', 2014, 'abc'], 
  [127931.772548, '生产一班', 2015, 'abc'], 
  [127931.772548, '生产一班', 2016, 'abc'], 
  [127931.772548, '生产一班', 2017, 'abc'], 
  [127931.772548, '生产一班', 2018, 'abc']
