Show all values ​​in js y axis chart

I have the following chart: Chart

I need letters along the y axis, so I added a switch to my chart options to start the corresponding letter for the y axis value. My problem is that the y axis only shows even numbers returning in half of the switch values ​​(xc, B, A +, etc.). But I want to show all the values ​​on the y axis, from 0 to 13. Is there any method to achieve this? Help is really appreciated.

var data = {
  labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
  datasets: [{
    label: "My First dataset",
    fill: false,
    lineTension: 0,
    backgroundColor: "rgba(75,192,192,0.4)",
    borderColor: "rgba(75,192,192,1)",
    borderCapStyle: 'butt',
    borderDash: [],
    borderDashOffset: 0.0,
    borderJoinStyle: 'miter',
    pointBorderColor: "rgba(75,192,192,1)",
    pointBackgroundColor: "#fff",
    pointBorderWidth: 2,
    pointHoverRadius: 5,
    pointHoverBackgroundColor: "rgba(75,192,192,1)",
    pointHoverBorderColor: "rgba(220,220,220,1)",
    pointHoverBorderWidth: 2,
    pointRadius: 1,
    pointHitRadius: 10,
    data: [0, 1, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13],
  }]
};

var options = {
  scales: {
    yAxes: [{
      ticks: {
        // Create scientific notation labels
        callback: function(value, index, values) {
          switch (value) {
            case 0:
              return 'XC';
            case 1:
              return 'C';
            case 2:
              return 'B';
            case 3:
              return 'A';
            case 4:
              return 'A+';
            case 5:
              return 'BA';
            case 6:
              return 'N+';
            case 7:
              return 'C-';
            case 8:
              return 'D+';
            case 9:
              return 'D';
            case 10:
              return 'D-';
            case 11:
              return 'N';
            case 12:
              return 'N-';
            case 13:
              return 'NR';
            default:
              return '';
              break;
          }
        }
      }
    }]
  }
};

var ctx = $('#chart');
var chart = new Chart(ctx, {
  type: 'line',
  data: data,
  options: options
});
