I'm trying to implement a graph with scattered date properties but chart is rendering all the dates with the same distance from each other.

```json
{
    "ndvi values": [
        0.1158,
        0.1975,
        0.1913,
        0.2137,
        0.1603,
        0.13,
        0.246,
        0.249,
        0.1955,
        0.124,
        0.1854,
        0.2721,
        0.2095,
        0.1357,
        0.2444
    ],
    "Julian dates": [
        2458208.0,
        2458386.0,
        2458476.0,
        2458566.0,
        2458653.0,
        2458746.0,
        2458836.0,
        2458921.0,
        2459026.0,
        2459111.0,
        2458391.0,
        2458476.0,
        2458566.0,
        2458746.0,
        2458836.0
    ]
}

```

This is the json data that I get from back-end api,the date array is something like this
[ 2018/2/12, 2018/218, 2018/5/19, 2019/1/1]. as you see the dates are ordered in the right and ascending way. is there any way making the graph steps more logical according to data that we have?
