如何为高级图表饼设置单独的颜色

Question

我可以通过传递series data.来获得高级图表，这可以为高级图表分配随机或主题颜色。

在以下示例中，我能够看到浅蓝色，黑色和绿色。但是，如何设置预定义的颜色。例如，我想改用橙色，红色和黄色。

// Build the chart
Highcharts.chart('container', {
    chart: {
        plotBackgroundColor: null,
        plotBorderWidth: null,
        plotShadow: false,
        type: 'pie'
    },
    title: {
        text: 'Browser market shares in January, 2018'
    },
    tooltip: {
        pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
    },
    plotOptions: {
        pie: {
            allowPointSelect: true,
            cursor: 'pointer',
            dataLabels: {
                enabled: false
            },
            showInLegend: true
        }
    },
    series: [{
        name: 'Brands',
        colorByPoint: true,
        data: [{
            name: 'Chrome',
            y: 61.41,
            sliced: true,
            selected: true
        }, {
            name: 'Internet Explorer',
            y: 11.84
        }, {
            name: 'Firefox',
            y: 10.85
        }]
    }]
});

<div id="container" style="min-width: 310px; height: 400px; max-width: 600px; margin: 0 auto"></div>

您可以使用setOptions为Highcharts中的颜色添加颜色，如下所示。

Highcharts.setOptions({
 colors: ['#ff6600', '#ff0000', '#ffff00']
});
// Build the chart
Highcharts.chart('container', {
    chart: {
        plotBackgroundColor: null,
        plotBorderWidth: null,
        plotShadow: false,
        type: 'pie'
    },
    title: {
        text: 'Browser market shares in January, 2018'
    },
    tooltip: {
        pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
    },
    plotOptions: {
        pie: {
            allowPointSelect: true,
            cursor: 'pointer',
            dataLabels: {
                enabled: false
            },
            showInLegend: true
        }
    },
    series: [{
        name: 'Brands',
        colorByPoint: true,
        data: [{
            name: 'Chrome',
            y: 61.41,
            sliced: true,
            selected: true
        }, {
            name: 'Internet Explorer',
            y: 11.84
        }, {
            name: 'Firefox',
            y: 10.85
        }]
    }]
});
