how to change display and styles of the labels in react-chartjs-2

I am using react-chartjs-2 and I want the labels to be circular. also I want the chart itself with labels have a display of inline-block so that I get something like this photo: [the desired design1

but what I actually get is this : the design of chartjs-2

and my code is here :

  let _data = data;
                let _backgroundColor = [];
                let _borderColor = [];
                setDataShareholder(res);
                res.value.forEach(item => {
                    let rgb = `${random(0, 255)}, ${random(0, 255)}, ${random(0, 255)}`;
                    _backgroundColor.push(`rgba(${rgb}, 0.5)`)
                    _borderColor.push(`rgba(${rgb}, 1)`)
                });
                _data.labels = res.value.map(item => item.name)
                _data.datasets = [{
                    data: res.value.map(item => Number(item.violationsCount)),
                    backgroundColor: _backgroundColor,
                    borderColor: _borderColor,
                    borderWidth: 1
                }];
                setData(_data);

usage :

  import { Doughnut } from 'react-chartjs-2';

  <Doughnut data={data} />

please help me if you can. thanks

Solution

  • You can configure the chart options. You can set the legend position to right and pointStyle to circle:

    const options = {
  type: 'doughnut',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3],
      backgroundColor: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"]
    }]
  },
  options: {
    plugins: {
      legend: {
        position: 'right',
        labels: {
          usePointStyle: true,
          pointStyle: 'circle'
        }
      }
    }
  }
}

const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
    <body>
  <canvas id="chartJSContainer" width="600" height="400"></canvas>
