lixianbin1 opened a new issue #8861: 关于区域选择的mousedown触发问题
URL: https://github.com/apache/incubator-echarts/issues/8861
 
 
   ### [问题简述]
   在IE11中，EChart的Line视图，在给canvas绑定mousedown后，当开启区域选择状态的时候，不会触发mousedown事件
   
   $("#poppup canvas").off("mousedown").on("mousedown",function(e){
     
   }
   $("#poppup canvas").on("mouseup",function(e){
   
   }
   
   ### [期望结果]
   希望能在IE的环境中，当我开启区域选择状态，开始拖动的时候能够触发mousedown事件,
   
   
   
   ### 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
   option = {
       xAxis: {
           type: 'category',
           data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
       },
       yAxis: {
           type: 'value'
       },
       series: [{
           data: [820, 932, 901, 934, 1290, 1330, 1320],
           type: 'line'
       }],
   	brush: {
   		toolbox: [ 'lineX'],
   		transformable:false,
   		xAxisIndex: 0,
   		brushStyle:{
   			borderWidth: 1,
   			color: 'rgba(78,200,247,0.1)',
   			borderColor: '#4ec8f7',
   		},
   	},
   };
   
   ```
