   ### Steps to Reproduce
   
   Hello, our usage scenarios are:
   The outermost label of the ring chart, and emphasis I set to false, because our use scene does not want him to display, just want to realize the scene of customized text in the center of the ring chart. There is no need to display the label, so our code is as follows, for example:
   In version 5.0.2, I set the label in the center of the ring chart like this
   option = {
       tooltip: {
           trigger:'item',
           formatter:'{a} <br/>{b}: {c} ({d}%)'
       },
       legend: {
           orient:'vertical',
           left: 10,
           data: ['Direct Access','Email Marketing','Affiliate Advertising','Video Advertising','Search Engine']
       },
       series: [
           {
              name:'Access source',
               type:'pie',
               radius: ['50%', '70%'],
               avoidLabelOverlap: false,
               label: {
                   show: false,
                   position:'center'
               },
               emphasis: {
                   label: {
                       show: false,
                       fontSize: '30',
                       fontWeight:'bold'
                   }
               },
               labelLine: {
                   show: false
               },
               data: [
                   {value: 335, name:'Direct access'},
                   {value: 310, name:'Email marketing'},
                   {value: 234, name:'Affiliate Ads'},
                   {value: 135, name:'Video ad'},
                   {value: 1548, name:'Search Engine'},
                   {label: {
                            normal: {
                 position:'center',
                 formatter: ['{c| }','{b| center label}', ].join('\n'),
                 show: true,
                 rich: {
                   b: {
                     color:'#333'
                   }
                 }
               }
                   }}
               ]
           }
       ]
   };
   Write down the center label directly as "center label", version 5.0.2 can take effect, and the four characters in the middle of the ring graph are displayed normally
   But with the same code, under version 5.2.1, this series.date.label is not valid, and these four texts cannot be displayed anymore.
   
   ### Current Behavior
   
   After upgrading from version 5.0.2 to version 5.2.1, the text in the middle of the ring chart cannot be displayed
   
   ### Expected Behavior
   
   It is expected that version 5.2.1, the text in the center of the ring chart can be displayed
   
   ### Environment
   
   ```markdown
   -OS:
   -Browser:
   -Framework:
   ```
