[Chartjs]-Change the style of the border in ChartJS

2👍

The Styling docs list all the config options for axis grid line configuration.

const ctx = document.getElementById('myChart').getContext('2d');

const myChart = new Chart(ctx, {
  type: 'bar',
  data: {
    labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3],
      backgroundColor: '#ffec87',
      borderWidth: 0,
      borderStyle: 'dotted'
    }]
  },
  options: {
    scales: {
      xAxis: { grid: { display: false } },
      yAxis: { grid: { borderDash: [8, 4] } }
    }
  }
});
