tz310200 opened a new issue #9990: Can I control the order of stack line charts 
with an attribute? 
URL: https://github.com/apache/incubator-echarts/issues/9990
 
 
   ### What problem does this feature solve?
   if I dynamically add a line, but the line is always at the top of the stack.
   ```javascrpt
   option = {
       title: {
           text: '折线图堆叠'
       },
       tooltip: {
           trigger: 'axis'
       },
       legend: {
           data:['邮件营销','联盟广告','视频广告','直接访问','搜索引擎']
       },
       grid: {
           left: '3%',
           right: '4%',
           bottom: '3%',
           containLabel: true
       },
       toolbox: {
           feature: {
               saveAsImage: {}
           }
       },
       xAxis: {
           type: 'category',
           boundaryGap: false,
           data: ['周一','周二','周三','周四','周五','周六','周日']
       },
       yAxis: {
           type: 'value'
       },
       series: [
           {
               name:'邮件营销',
               type:'line',
               stack: '总量',
               data:[120, 132, 101, 134, 90, 230, 210]
           },
   
           {
               name:'视频广告',
               type:'line',
               stack: '总量',
               data:[150, 232, 201, 154, 190, 330, 410]
           },
           {
               name:'直接访问',
               type:'line',
               stack: '总量',
               data:[320, 332, 301, 334, 390, 330, 320]
           },
           {
               name:'搜索引擎',
               type:'line',
               stack: '总量',
               data:[820, 932, 901, 934, 1290, 1330, 1320]
           }
       ]
   };
   setTimeout(function() {
       myChart.setOption({
           series: [{        
               name:'联盟广告',
               type:'line',
               stack: '总量',
               data:[220, 182, 191, 234, 290, 330, 310]
           }].concat(option.series)
       })
       
   }, 1000);
   ```
   I want series-line '联盟广告' at the bottom

   ### What does the proposed API look like?
   ```
   series: [
           {
               index: 0 // Control stack line order
               name:'邮件营销',
               type:'line',
               stack: '总量',
               data:[120, 132, 101, 134, 90, 230, 210]
           },
   ]
   ```
