I have a JSON Store where one of the indexes is an array of arrays.
For example:

Code:
{
      "data": [[ 1, 2, 3 ],[1,2,3],[1,2,3]]
}
I want to use data[0], data[1], and data[2] as a dataIndex for a grid.

Code:
  grid = new Ext.grid.GridPanel({
          store: store,
	  series: [{    
					type: 'area',
					name: 'data1',
					pointInterval: 24 * 3600 * 1000,
					pointStart: Date.UTC(2010, 0, 01),
					dataIndex: data[0]
				},{    
					type: 'area',
					name: 'data2',
					pointInterval: 24 * 3600 * 1000,
					pointStart: Date.UTC(2010, 0, 01),
					dataIndex: data[1]
				},{    
					type: 'area',
					name: 'data2',
					pointInterval: 24 * 3600 * 1000,
					pointStart: Date.UTC(2010, 0, 01),
					dataIndex: data[2]
				}]

...

This, however, doesn't work. Any suggestions?
