zaiMoe opened a new issue #10033: symbolSize如何自定义hover时的大小
URL: https://github.com/apache/incubator-echarts/issues/10033
 
 
   ### Version
   3.7.2
   
   ### Reproduction link
   [https://www.echartsjs.com/examples/editor.html?c=scatter-punchCard](https://www.echartsjs.com/examples/editor.html?c=scatter-punchCard)
   
   ### Steps to reproduce
   复制并替换成下面的代码，然后悬停在某个symbol上：
   ```
   var hours = [];
   
   var date = new Date();
   var time = date.getTime();
   
   for (var n = 0; n < 100; n++ ) {
       // hours.push(time   1000 * 60 * 60 * n);
       hours.push(n+1)
   }
   
   var days = ['Saturday', 'Friday', 'Thursday',
       'Wednesday'];
   
   var data = [];
   
   for (var i = 0; i < 4; i++) {
       for (var j = 0; j < hours.length; j++ ) {
           data.push([j, i, Math.random() * 10])
       }
   }
   
   option = {
       tooltip: {
           formatter: function (params) {
               return params.value[2];
           }
       },
       xAxis: {
           type: 'category',
           data: hours,
           boundaryGap: false,
           axisLine: {
               show: true
           }
       },
       yAxis: {
           type: 'category',
           data: days,
           axisLine: {
               show: true
           }
       },
       series: [{
           name: 'Punch Card',
           type: 'scatter',
           symbol: 'rect',
           symbolSize: function (val) {
               return [1, 20];
           },
           data: data,
           animationDelay: function (idx) {
               return idx * 5;
           }
       }]
   };
   ```
   
   ### What is expected?
   能自定义symbolSize
   
   ### What is actually happening?
   symbolSize在hover时的放大比例不受控
   
   ---
   散点图自定义了symbol:rect， symbolSize: [1, 20]
   导致hover的时候放大比例异常，目前通过设置hoverAnimation: false和itemStyle.emphasis来简单的实现hover变化，有其他更好的解决方法吗？
