当前,我面临一个问题,我需要使用Highchart在饼图中手动设置不透明度。如果您知道要分配给切片的颜色,则以下解决方案效果很好。但是,如果从通用调色板中选择颜色,则无法给出不透明度。它始终为0。因为有人可以帮我吗?

$(function () {
    $('#container').highcharts({
        chart: {
            plotBackgroundColor: null,
            plotBorderWidth: null,
            plotShadow: false,
        },
        title: {
            text: 'Browser market shares at a specific website, 2010'
        },
        tooltip: {
    	    pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
        },
        plotOptions: {
            pie: {
                allowPointSelect: true,
            fillOpacity: 0.5,
                cursor: 'pointer',
                dataLabels: {
                    enabled: true,
                    color: '#000000',
                    connectorColor: '#000000',
                    format: '<b>{point.name}</b>: {point.percentage:.1f} %'
                }
            }
        },
        series: [{
            type: 'pie',
            name: 'Browser share',
            data: [
                ['Firefox',   45.0],
                ['IE',       26.8],
                {
                    name: 'Chrome',
                    y: 12.8,
                    sliced: true,
                    selected: true,
                    color: 'rgba(150,100,50,0.1)'
                },
                ['Safari',    8.5],
                ['Opera',     6.2],
                ['Others',   0.7]
            ]
        }]
    });
});

您可以使用opacity方法设置attr

        events: {
            load: function() {
                var points = this.series[0].points;

                points[1].graphic.attr({
                    opacity: 0.4
                })
            }
        }
