$('.chart-container').append('<canvas id="myChart" style="height:400vh; width:500vw;"></canvas>');



let options = {
spanGaps: true,
responsive: true,
maintainAspectRatio : false,
scales: {
    xAxes:[{
        afterFit:(axis)=>{
            // console.log(axis)
            axis.paddingLeft = 25;
            axis.paddingRight = 15;
        },
        // padding : 20,
        ticks: {
            fontSize: 15,
            padding :20,
            drawTicks:true,
            offset: true,

        },
        gridLines:{
            display: xLineState,
            lineWidth: xLine,
            // offsetGridLines: true
        },

You are doing nothing wrong, it seems like it is a bug in chart.js. version 2.4.0 is the latest version I can see it works in.

Working example:

var options = {
  type: 'line',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
        label: '# of Votes',
        data: [12, 19, 3, 5, 2, 3],
        borderWidth: 1
      },
      {
        label: '# of Points',
        data: [7, 11, 5, 8, 3, 7],
        borderWidth: 1
      }
    ]
  },
  options: {
    scales: {
      xAxes: [{
        afterFit: (axis) => {
          // console.log(axis)
          axis.paddingLeft = 25;
          axis.paddingRight = 15;
        },
      }],
      yAxes: [{
        ticks: {
          reverse: false
        }
      }]
    }
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
canvas {
  background-color: #eee;
}

<body>
  <canvas id="chartJSContainer" width="600" height="400"></canvas>
</body>
