React chart : prevent chart's canvas scaling with height and width

Question

I am using Horizontal Bar from react-chart-js (https://github.com/reactchartjs/react-chartjs-2/blob/react16/example/src/charts/HorizontalBar.js) as below,

  const data = {
    label: ["graph"],
    datasets: [
      {
        label: "A",
        backgroundColor: "red",
        data: [50],
      },
      {
        label: "B",
        backgroundColor: "yellow",
        data: [10],
      },
    ],
  };

  const chartOptions = {
    scales: {
      xAxes: [
        {
          stacked: true,
          barPercentage: 0.2,
        },
      ],
      yAxes: [
        {
          stacked: true,
          barPercentage: 0.2,
        },
      ],
    },
  };

and

<div>
  <HorizontalBar data={data} options={chartOptions}/>
</div>

I tried applying height on to div or horizontal bar directly to restrict scaling up of the canvas but it dint solve though. Is it possible to supply height and width to the canvas of chart respectively.

Answer 1

In my case, setting maintainAspectRatio:false along with supplying height/width on div

<div style={{height:'100px',width:'200px'}}>
<HorizontalBar data={data} options={chartOptions}/>
</div>

helped in restricting the canvas's scalability.

Answer 2

Try setting responsive: false in your options object. That should according to the documentation make so that the canvas doesn't resize (https://www.chartjs.org/docs/latest/general/responsive.html#configuration-options)
