Chartjs-Label on the x-axis does not show completely in Chart.js

This is because by default the time scale auto generates ticks, if you dont want to include the labels from your data you need to set ticks.source to data:

options: {
  scales: {
    x: {
      type: 'time',
      ticks: {
        source: 'data'
      }
    }
  }
}
