how to make chartjs columns smaller in width for bar chart?

November 5, 2021

I have a chartJS chart and I don’t understand how to make the columns smaller in width when there are few of them

>Solution :

You can use the barPercentage for that:

var options = {
  type: 'bar',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
        label: '# of Votes',
        data: [12, 19, 3, 5, 2, 3],
        backgroundColor: 'pink'
      },
      {
        label: '# of Points',
        data: [7, 11, 5, 8, 3, 7],
        backgroundColor: 'orange'
      }
    ]
  },
  options: {
    indexAxis: 'y',
    barPercentage: 0.4,
    scales: {
      x: {
        stacked: true
      },
      y: {
        stacked: true
      }
    }
  }
}

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