I want to create two bar in Jan column

I'm not sure I understand your question. Are you trying to render two bars? In that case you need another group in your data:

[
  {
    "name": "Germany",
    "series": [
      {
        "name": "2010",
        "value": 7300000
      },
      {
        "name": "2011",
        "value": 8940000
      }
    ]
  },
​
  {
    "name": "USA",
    "series": [
      {
        "name": "2010",
        "value": 7870000
      },
      {
        "name": "2011",
        "value": 8270000
      }
    ]
  }
]
