### 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
