echarts pie 循环动图

直接上代码

  var mycharts=echarts.init(document.getElementById("你的divId"))
option = {series : [{name: '访问来源',type: 'pie',radius: '55%',data:[{value:235, name:'视频广告'},{value:274, name:'联盟广告'},{value:310, name:'邮件营销'},{value:335, name:'直接访问'},{value:400, name:'搜索引擎'}],roseType: 'angle',itemStyle: {normal: {shadowBlur: 200,shadowColor: 'rgba(0, 0, 0, 0.5)'}}}]
};mycharts.setOption(option);tools.loopShowTooltip(mycharts, option, {loopSeries: true});

JS 代码

  (function (global) {global.tools = global.tools || {};tools.loopShowTooltip = function (chart, chartOption, options) {var defaultOptions = {interval: 2000,loopSeries: false,seriesIndex: 0,updateData: null};if (!chart || !chartOption) {return {};}var dataIndex = 0; // 数据索引，初始化为-1，是为了判断是否是第一次执行var seriesIndex = 0; // 系列索引var timeTicket = 0;var seriesLen = chartOption.series.length; // 系列个数var dataLen = 0; // 某个系列数据个数var chartType; // 系列类型var first = true;//不循环series时seriesIndex指定显示tooltip的系列，不指定默认为0，指定多个则默认为第一个//循环series时seriesIndex指定循环的series，不指定则从0开始循环所有series，指定单个则相当于不循环，指定多个//要不要添加开始series索引和开始的data索引？if (options) {options.interval = options.interval || defaultOptions.interval;options.loopSeries =  options.loopSeries || defaultOptions.loopSeries;options.seriesIndex = options.seriesIndex || defaultOptions.seriesIndex;options.updateData = options.updateData || defaultOptions.updateData;} else {options = defaultOptions;}//如果设置的seriesIndex无效，则默认为0if (options.seriesIndex < 0 || options.seriesIndex >= seriesLen) {seriesIndex = 0;} else {seriesIndex = options.seriesIndex;}function autoShowTip() {function showTip(){//判断是否更新数据if(dataIndex === 0 && !first && typeof options.updateData === "function") {options.updateData();chart.setOption(chartOption);document.getElementById('pie1Word').innerHTML = dataIndex;}var series = chartOption.series;chartType = series[seriesIndex].type; // 系列类型dataLen = series[seriesIndex].data.length; // 某个系列的数据个数var tipParams = {seriesIndex: seriesIndex};switch(chartType) {case 'map':case 'pie':case 'chord':tipParams.name = series[seriesIndex].data[dataIndex].name;break;case 'radar': // 雷达图tipParams.seriesIndex = seriesIndex;tipParams.dataIndex = dataIndex;break;default:tipParams.dataIndex = dataIndex;break;}if(chartType === 'pie' || chartType === 'radar') {// 取消之前高亮的图形chart.dispatchAction({type: 'downplay',seriesIndex: options.loopSeries ?
