echarts 旭日图sunburst[通俗易懂]

1、配置数据
 	数据结构上,内圈是外圈的父节点
	[
		{
		 	value:n,   
		 		数值,根据同层所有数值的占比,构成百分比圆环,不写为内部第一层children的数值和
		 		若设置的值大于内部第一层的数值,即表示有未显示的内容,具体表示图会压缩同层其他环占比
		 	name:'显示内容',
		 	link:'点击此节点可跳转的超链接',	nodeClick值为'link'时才生效
		 	target = 'blank|self',			nodeClick值为'link'时才生效
		 	r:n|n%,		该层圆环的内半径,设置后radius无效
		 	r0:n|n%,	该层圆环的外半径,设置后radius无效
		 	children:[
			 {
			 	value:n,
				name:'显示内容'
			 }
			]
		},
		{
			value:n,
			name:''
		}
	]

2、配置series
 series:[
	{
	    type:'sunburst',
	    center:['50%','50%'],
	    radius = [0, '75%'],  内半径,外半径
        sort:function(nodeA, nodeB) {  对数值进行排序后再展示
          return -nodeA.getValue() + nodeB.getValue()
        },
        highlightPolicy:'ancestor',  高亮是圆环显示形式
        	'descendant'，则会高亮该扇形块和后代元素，其他元素将被淡化
        	'ancestor'，则会高亮该扇形块和祖先元素；
            'self' 则只高亮自身；
            'none' 则不会淡化其他元素。
       nodeClick:'zoomToNode'	点击节点后缩放到节点
	       	false：节点点击无反应
			'link'：如果节点数据中有 link 点击节点后会进行超链接跳转。
	   sort:'desc|asc|null'	扇形块根据数据value的排序方式,如果未指定value,则其值为子元素value之和
		 	function(nodeA, nodeB) {
			    return nodeA.getValue() - nodeB.getValue();
			}
	   label:{
	   	 rotate:'radial'	径向旋转
	   	 	'tangential' 	切向旋转
	   	 	n数字
	   },
       levels:[  设置各个层级圆环样式
		{
			第一层表示,点击后中间空白圆圈的样式,即点击返回的圆圈
			itemStyle:{}
		},
		{
			第二层设置最内层圆环的样式
			label:{},
			itemStyle:{},
			emphasis:{}, 高亮样式
			highlight:{}, 鼠标悬停后相关扇形块的配置项
			downplay:{ 从本层开始,未悬停区域的颜色
				label:{},
				itemStyle:{}
			}
		}
	   ]
