	};
// Apply the theme
var highchartsOptions = Highcharts.setOptions(Highcharts.theme);

1.在js文件中导入上面主题

2.创建图表前加入渐变代码

 Highcharts.getOptions().colors = Highcharts.map(
		Highcharts.getOptions().colors, function(color) {
			return {
				radialGradient : {
					cx : 0.5,
					cy : 0.3,
					r : 0.7
				},
				stops : [
						[ 0, color ],
						[
								1,
								Highcharts.Color(color).brighten(0.3).get(
										'rgb') ] // darken
				]
			};
	});

3.加载数据时选择颜色_colorIndex

series: [{
        	_colorIndex: 0,
            name: '新异常',
            data: errorStateNew,
            stack: 'male'
        }, {
        	_colorIndex: 1,
            name: '已处理',
            data: errorStateFinish ,
            stack: 'male'
        }, {
        	_colorIndex: 2,
            name: '废弃',
            data: errorStateDiscard,
          stack: 'male'
        }]
