Positioning customized data on the doughnut chart within chart.js

Is there a way to customize the position of the data displayed in a doughnut chart? Currently, the default setting is that the first item in the data array is placed at 0 degrees. However, I need to place it at a custom position because I am working on a clock-related app.https://i.stack.imgur.com/FPaV7.jpg

this.doughnutChart = new Chart(this.doughnutCanvas.nativeElement, {

      type: 'doughnut',
      data: {
        labels: this.titles,
        datasets: [{
          label: '# of Votes',
          data: this.times,
          backgroundColor: [
            'rgba(255, 99, 132, 0.5)',
            'rgba(54, 162, 235, 0.5)'
          ],
          hoverBackgroundColor: [
            "#FF6384",
            "#36A2EB"
          ]
        }]
      },
      options: {
        legend: {
          display: false
        }
      }
    });

Answer №1

Play around with the rotation setting:

customization: {
    rotation: -0.5 * Math.PI
}

The default value shown above (-0.5 * Math.PI) is what is commonly used. If you input a value of 0, it will rotate the doughnut chart by 90° clockwise. For your specific requirements, make sure to enter a value between 0.5 * Math.PI and 1.0 * Math.PI. Further details are available in the documentation.
