I have a timeseries data which I am trying to display with Highstocks:
Here is the data:

```
{
  "title": {
    "text": "My Graph"
  },
  "series": [
    [
      {
        "name": "Future Index Longs",
        "data": [
          [
            "2019-02-05",
            104516
          ],
          [
            "2019-02-06",
            127260
          ],
          [
            "2019-02-07",
            156291
          ],
          [
            "2019-02-08",
            167567
          ]
        ]
      }
    ],
    [
      {
        "name": "Future Index Longs",
        "data": [
          [
            "2019-02-05",
            21
          ],
          [
            "2019-02-06",
            0
          ],
          [
            "2019-02-07",
            1263
          ],
          [
            "2019-02-08",
            12
          ]
        ]
      }
    ],
    [
      {
        "name": "Future Index Longs",
        "data": [
          [
            "2019-02-05",
            33873
          ],
          [
            "2019-02-06",
            61093
          ],
          [
            "2019-02-07",
            43125
          ],
          [
            "2019-02-08",
            41928
          ]
        ]
      }
    ],
    [
      {
        "name": "Future Index Longs",
        "data": [
          [
            "2019-02-05",
            47542
          ],
          [
            "2019-02-06",
            55084
          ],
          [
            "2019-02-07",
            75256
          ],
          [
            "2019-02-08",
            77786
          ]
        ]
      }
    ],
    [
      {
        "name": "Future Index Longs",
        "data": [
          [
            "2019-02-05",
            185952
          ],
          [
            "2019-02-06",
            243437
          ],
          [
            "2019-02-07",
            275935
          ],
          [
            "2019-02-08",
            287293
          ]
        ]
      }
    ]
  ]
}

```

The graph is empty and no data is displayed. What am I doing wrong?

Sorry to add this filler here but I am required to add more text to post this question and since this is a pretty simple question, I don't have much to add.
