High Charts : Two lines showing instead of one

I,m working with highcharts.js

The issue is while creating a graph its showing me two lines instead of one.

It should only show me one line because its ploting the graph between 2 values which are (timestamp and value).

Can you please check why its showing me two lines instead of one and how can i fix this :

(Just copy and paste the code in a file and it should work).

<!DOCTYPE html>
<html>

<head>

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.highcharts.com/highcharts.js"></script>

</head>

<body style="background:#212224;">

<div id="container" style="max-width: 1666px;  margin: 0 auto"></div>

<script type="text/javascript">

    $.getJSON('https://dl.dropboxusercontent.com/u/76618626/data4.json', function (data) {
        console.log("data size is : ");
        console.log(data);      

        var data3 = [];

                    $.each(data.data,function(i,d){
                    console.log(new Date(d.timestamp).getTime(), d.value);

                        data3.push([new Date(d.timestamp).getTime(),d.value]);

                    });

                    console.log("Data 3 is :");
                    console.log(data3);
                    var data4 = [];
                    Highcharts.each(data3, function(p, i) {
                        if (typeof p[0] !== 'number' || typeof p[1] !== 'number') {
                             console.log('Invalid data is :')
                             console.log(p);
                        } else {
                            data4.push(p);
                        }
                    });



        $('#container').highcharts({

            chart: {
            backgroundColor: '#000000',
                },

            title: {
                text: 'Test Graph',
                style: {
                color: '#FFFFFF',
                fontWeight: 'bold'
                }
            },
            xAxis: {
                type: 'datetime',
                title: {

            },

                enabled: true
            },

            exporting: false,



            plotOptions: {
                line: {                 
                    lineColor: 'red',
                    fillOpacity: 1,                    
                    lineWidth: 2,
                    states: {
                        hover: {
                            lineWidth: 2
                        }

                    threshold: null,
                    marker: {
                        fillColor: '#e57255'
                        }


                },


            },


            series: [{
                type: 'line',
                name: 'test',
                data: data4
            }]
        });
    });

I rewrote your code in jsFiddle. It is actually a single Line chart.

Check out the print out at console.log(new Date(d.timestamp).toString(), d.value);.

Your data's timestamps start from Tue Jul 05 2016 03:00:00, increase to Thu Jul 07 2016 03:00:00, and starts again from Jul 05 2016 03:00:00.

Hence this is why your chart seems like a two-line chart. The bottom part of the line is being linked back to the top line.

Just update your data JSON and you will be good.

Edited:

Update my fiddle to arrange timestamps using .sort().
