防止画布图表JS的大小等于窗口的高度和宽度

Question

I am using chartjs to display data and the chart (canvas) takes up 100% width and 100% height of the window.

I want to reduce this to be 600px by 600px . To do this I tried using Chart.defaults.global.legend.fullWidth = false; however this didn't work.

I have created a jsfiddle her e for your convenience.

See code below:

HTML

<canvas id="myChart" width="400" height="400"></canvas>

JS

var ctx = document.getElementById("myChart");
Chart.defaults.global.defaultFontColor = "#000";
Chart.defaults.global.legend.fullWidth = false;
var myChart = new Chart(ctx, {
    type: 'pie',
    data: {
        labels: labels,
        datasets: [{
            label: '# of Followers',
            data: followers,
            backgroundColor: [
                'rgba(255, 99, 132, 0.9)',
                'rgba(54, 162, 235, 0.9)',
                'rgba(255, 206, 86, 0.9)',
                'rgba(75, 192, 192, 0.9)',
                'rgba(153, 102, 255, 0.9)',
                'rgba(255, 159, 64, 0.9)'
            ],
            borderColor: [
                'rgba(255,99,132,1)',
                'rgba(54, 162, 235, 1)',
                'rgba(255, 206, 86, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(153, 102, 255, 1)',
                'rgba(255, 159, 64, 1)'
            ],
            borderWidth: 5
        }]
    },
    options: {
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero:true
                }
            }]
        }
    }
});

Add 'responsive: false' to the chart options

options: {
        responsive: false,
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero:true
                }
            }]
        }
    }
