Solution

I suggest you Scatter Chart. In Scatter Charts, you can draw multiple independent lines. As you can see from the below image.

[Sample Code]

var scatterChart = new Chart(ctx1, {
        type: 'line',
        data: {
            datasets: [
            {

                label: 'Scatter Dataset',
                backgroundColor: "rgba(246,156,85,1)",
                borderColor: "rgba(246,156,85,1)",
                fill: false,
                borderWidth : 15,
                pointRadius : 0,
                data: [
                    {
                        x: 0,
                        y: 9
                    }, {
                        x: 3,
                        y: 9
                    }
                ]
            },
            {
                backgroundColor: "rgba(208,255,154,1)",
                borderColor: "rgba(208,255,154,1)",
                fill: false,
                borderWidth : 15,
                pointRadius : 0,
                data: [
                    {
                        x: 3,
                        y: 7
                    }, {
                        x: 5,
                        y: 7
                    }
                ]
            },
            {

                label: 'Scatter Dataset',
                backgroundColor: "rgba(246,156,85,1)",
                borderColor: "rgba(246,156,85,1)",
                fill: false,
                borderWidth : 15,
                pointRadius : 0,
                data: [
                    {
                        x: 5,
                        y: 5
                    }, {
                        x: 10,
                        y: 5
                    }
                ]
            },
            {
                backgroundColor: "rgba(208,255,154,1)",
                borderColor: "rgba(208,255,154,1)",
                fill: false,
                borderWidth : 15,
                pointRadius : 0,
                data: [
                    {
                        x: 10,
                        y: 3
                    }, {
                        x: 13,
                        y: 3
                    }
                ]
            }
            ]
        },
        options: {
            legend : {
                display : false
            },
            scales: {
                xAxes: [{
                    type: 'linear',
                    position: 'bottom',
                    ticks : {
                        beginAtzero :true,
                        stepSize : 1
                    }
                }],
                yAxes : [{
                    scaleLabel : {
                        display : false
                    },
                    ticks : {
                        beginAtZero :true,
                        max : 10
                    }
                }]
            }
        }
    });

Rest the configuration like colors or if you want to hide the y axes do it as your project required.
