Chartjs-How to fix chart not starting at zero

I assume you are using v3 since in v2 this is the correct syntax, in v3 the scales are no arrays anymore but just objects, for all changes you can read the migration guide (https://www.chartjs.org/docs/master/getting-started/v3-migration.html)

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
    }]
  },
  options: {
    scales: {
      y: {
        beginAtZero: true,
      }
    }
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
  <canvas id="chartJSContainer" width="600" height="400"></canvas>

</body>
