如何更改highcharts饼图的颜色？

Question

我正在使用highcharts制作饼图,但我在为图表加载自定义颜色集时遇到问题.

这是我的代码:

     <script type="text/javascript">
     $(function () {
     Highcharts.setOptions({
     colors: ['#50B432', '#ED561B', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263',      '#6AF9C4']
    });
    return new Highcharts.Chart({


        chart: {
            renderTo: 'trailpiechart',
            plotBackgroundColor: null,
            plotBorderWidth: null,
            plotShadow: false,
            backgroundColor: "#f8f8f8",
            margin: [20, 20, 20, 20]
        },


        credits: {
            enabled: false
        },

        title: {
            text: caption
        },
        tooltip: {
            formatter: function () {
                return this.y + ' links';
            }
        },
        plotOptions: {
            pie: {
                allowPointSelect: true,
                cursor: 'pointer',
                dataLabels: {
                    enabled: false
                },
                showInLegend: true
            }
        },
        legend: {
            layout: 'vertical',
            floating: false,
            borderRadius: 0,
            borderWidth: 0
        },
        series: [{
            type: 'pie',
            name: 'Browser share',
            data: data
        }]
    });
    });
</script>

我的饼图使用此代码,但它只使用默认颜色托盘.

Answer 1

Highcharts.setOptions({
 colors: ['#50B432', '#ED561B', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4']
});

对于那些喜欢初始化配置中颜色的人,你可以简单地将颜色放在配置对象的plotOptions部分中,如下所示:

...,
plotOptions: {
  pie: {
   colors: [
     '#50B432', 
     '#ED561B', 
     '#DDDF00', 
     '#24CBE5', 
     '#64E572', 
     '#FF9655', 
     '#FFF263', 
     '#6AF9C4'
   ],
   allowPointSelect: true,
   cursor: 'pointer',
   dataLabels: {
     enabled: false
   },
   showInLegend: true
 }
},
...

我认为您需要做的是使用theme而不是setOptions设置颜色,如下所示:

Highcharts.theme = {colors: ['#50B432', '#ED561B', '#DDDF00', '#24CBE5', 
                             '#64E572', '#FF9655', '#FFF263', '#6AF9C4']});
