astik opened a new issue #8294: inconsistencies between yAxis.axisLabel and yAxis.axisPointer.label formatters
URL: https://github.com/apache/incubator-echarts/issues/8294
 
 
   ### inconsistencies between yAxis.axisLabel and yAxis.axisPointer.label formatters with string configuration (interpolation seems to give different results)
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]: 4.x
   + Browser version [浏览器类型和版本]: tested with chrome 66.0.3359.139 and firefox 59.0.2, but i don't think it matters
   + OS Version [操作系统类型和版本]: tested with osx 10.13.3, but i don't think it matters
   
   ### Expected behaviour [期望结果]
   
   Formatter with same configuration should give the same result for both labels (yAxis.axisLabel and yAxis.axisPointer.label).
   
   ### ECharts option [ECharts配置项]
   ```javascript
   option = {
       tooltip: {
           trigger: 'axis',
   			axisPointer: {
   				type: 'cross'
   			}
       },
       xAxis: {
           type: 'category',
           data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
       },
       yAxis: {
           type: 'value',
           axisLabel: {
               formatter: '{value}'
           },
           axisPointer: {
               label:{
                   formatter: '{value}'
               }
           }
       },
       series: [
           {
               name:'A',
               type:'line',
               data:[120000.5, 132000.5, 101000.5, 134000.5, 90000.5, 230000.5, 210000.5]
           },
           {
               name:'B',
               type:'line',
               data:[220000.5, 282000.5, 201000.5, 234000.5, 290000.5, 430000.5, 410000.5]
           }
       ]
   };
   ```
   
   With this configuration, you'll end-up with :
   
   * yAxis.axisLabel will display "120000.5" for 120000.5
   * yAxis.axisPointer.label will display "120,000.5" for 120000.5
   
   To get a consistent display, you'll need to have this configuration :
   
   ```javascript
   option = {
       tooltip: {
           trigger: 'axis',
   			axisPointer: {
   				type: 'cross'
   			}
       },
       xAxis: {
           type: 'category',
           data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
       },
       yAxis: {
           type: 'value',
           axisLabel: {
               formatter: '{value}'
           },
           axisPointer: {
               label:{
                   formatter: function(a){return a.value.toFixed(2)}
               }
           }
       },
       series: [
           {
               name:'A',
               type:'line',
               data:[120000.5, 132000.5, 101000.5, 134000.5, 90000.5, 230000.5, 210000.5]
           },
           {
               name:'B',
               type:'line',
               data:[220000.5, 282000.5, 201000.5, 234000.5, 290000.5, 430000.5, 410000.5]
           }
       ]
   };
   ```
