HighCharts not displaying series data - highcharts

Question

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.

Answer 1

You have the wrong format on your series, it should be an array of objects.
Like this: series: [{ ... }, { ... }]

Answer 2

To have a chart with datetime axes in Highcharts you have to pass the X value as the timestamp in milliseconds since 1970.
Highstock example:

Note that in Highcharts you have to define xAxis.type as datetime like that:
xAxis: {
type: 'datetime'
}
