MohammadYounes opened a new issue #11080: Gauge - Anticlockwise
URL: https://github.com/apache/incubator-echarts/issues/11080
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   Create a gauge with the following option
   
   ```js
   option = {
       series: [
           {
               type: 'gauge',
               detail: {formatter:'{value}%'},
               data: [{value: 50}],
               min:0,
               max:100,
               startAngle:0,
               endAngle:180,
               clockwise:false //anitclockwise
           }
        ]
   }
   ```

   However, setting `clockwise` to `true` breaks the axis line.
   
   ```js
   option = {
       series: [
           {
               type: 'gauge',
               detail: {formatter:'{value}%'},
               data: [{value: 50}],
               min:0,
               max:100,
               startAngle:0,
               endAngle:180,
               clockwise:true
           }
        ]
   }
   ```

   ### What is expected?
   The gauge to be created **anticlockwise** along with the pointer animation.
   
   ### What is actually happening?
   Both the gauge and pointer animation are **clockwise**.
   
   ---
   The only way I could make it anticlockwise was by swapping `min`/`max` and 
`startAngle`/`endAngle`. But unfortunately, the pointer animation remained 
clockwise.
   
   ```js
   option = {
       series: [
           {
               type: 'gauge',
               detail: {formatter:'{value}%'},
               data: [{value: 50}],
               min:100,
               max:0,
               startAngle:180,
               endAngle:0,
               clockwise:true
           }
       ]
   }
   ```
