   ### One-line summary [问题简述]
   line图中，svg渲染时，setOption控制label的显示无效
   需求是系列太多，label会出现重叠，所以toolbox里加了个控制显示隐藏功能
   
   
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]:源码里怎么看echart和zrender的版本？能在抬头的注释里写下么~~
   + Browser version [浏览器类型和版本]:chrome
   + OS Version [操作系统类型和版本]:
   
   
   
   
   
   ### Expected behaviour [期望结果]
   能控制label的显示和隐藏
   
   
   
   
   ### ECharts option [ECharts配置项]
   <!-- Copy and paste your 'echarts option' here. -->
   <!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 option。如何得到能运行的 option 参见上方的 guidelines for contributing] -->
   ```javascript
   var dom = document.getElementById("container");
   var myChart = echarts.init(dom, null, {renderer: 'svg'});
   //echarts.init(dom);  默认canvas是OK的
   var app = {};
   var check = false;
   option = null;
   option = {
       xAxis: {
           type: 'category',
