You can filter your data beforeHand and use object notation togehter with it:

let initialData = [{
    "x": "label1",
    "y": 9
  },
  {
    "x": "label2",
    "y": 0
  },
  {
    "x": "label3",
    "y": 5
  },
  {
    "x": "label4",
    "y": 10
  },
  {
    "x": "label6",
    "y": null
  },
  {
    "x": "label7",
    "y": 3
  },
  {
    "x": "label8",
    "y": undefined
  }
];
let data = initialData.filter(e => e.y);

const options = {
  type: 'bar',
  data: {
    datasets: [{
      label: '# of Votes',
      data: data,
      backgroundColor: 'pink',
    }]
  },
  options: {}
}

const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
