How to remove padding Chart js

I use Chart js with options:

  options: {
    scales: {
      xAxes: [{
        ticks: {
          autoSkip: false,
          beginAtZero: true,
          min: 0,
          beginAtZero: true,
        },
      }],
      yAxes: [{
        ticks: {
          beginAtZero: true,
          min: 0,
          beginAtZero: true,
        },
      }]
    }
  }

How to remove this padding? I cant find this option in documentation.
