[Chartjs]-Vertical Gird Line Issue with Chart.js

✅

Ok, this might be weird, but I just removed every '' from the labels array and it renders like it should.

jsFiddle

Chart.defaults.global.elements.point.radius = 2;

var ctx = document.getElementById("graph-1-met");

var myLineChart = new Chart(ctx, {
  type: 'line',
  data: {
    labels: [0, , , , , 1, , , , , , 2, , , , , , 3, , , , , , 4, , , , , , 5, , , , , , 6, , , , , , 7, , , , , , 8, , , , , , 9, , , , , , 10, , , , , , 11, , , , , , 12, , , , , , 13, , , , , , 14, , , , , , 15, , , , , ],
