更改hightcharts（饼图）的大小

Question

我是highcharts的新手，并成功创建了饼图。但我想在宽度为33％的div中显示它，因此饼图的大小很小，标签的宽度比饼图宽。

我想减少标签的宽度或长度，增加饼图的面积

这是代码

var css = ClaimSubmissionStatus;// its array getting form backend
        css.splice(0, 1);
        var mycss = css;

        var chart = {
            plotBackgroundColor: null,
            plotBorderWidth: null,
            plotShadow: false
        };

        var tooltip = {
            pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
        };
        var plotOptions = {
            pie: {
                allowPointSelect: true,
                cursor: 'pointer',
                point: {
                    events: {
                        click: function () {
                            alert('Category: ' + this.x + ', value: ' + this.y);
                        }
                    }
                },
                dataLabels: {
                    enabled: true,
                    format: '<b>{point.name}%</b>: {point.percentage:.1f} %',
                    style: {
                        color: (Highcharts.theme && Highcharts.theme.contrastTextColor) ||
                        'black'
                    }
                }
            }
        };
        var series = [{
            type: 'pie',
            animation: false,
            name: '',
            data: mycss,
        }];
        var json = {};
        json.chart = chart;


        json.series = series;
        json.plotOptions = plotOptions;
        $('#divClaimSubmission').highcharts(json);
