This is the data format you may need to generate in order to use with NVD3 chart.

[
    {
        "key": "Stream0",
        "values": [
            {
                "x": 0,
                "y": -0.14263036487474057
            },
            {
                "x": 1,
                "y": -0.1331488246687006
            }
        ],
        "type": "line",
        "yAxis": 1
    },
    {
        "key": "Stream1",
        "values": [
            {
                "x": 0,
                "y": -0.27248210886232416
            },
            {
                "x": 1,
                "y": -0.28823740073421067
            }
        ],
        "type": "bar",
        "yAxis": 2
