**TITLE**
[Feature] When the data is empty, the label will not be displayed, and it is
hoped that the label can be displayed
**BODY**
### What problem does this feature solve?
I want to display a custom label when the data is empty, I want to ask if
there is a configuration item that allows displaying the label when the data is
empty?
The following configuration data is an example:
```
option = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [
{
data: [150, 230, '-', 218, 135, 147, 260],
type: 'line',
label: {
show: true,
formatter: (params) => {
if(!params.data) {
return 'No data'
}
return 'has data'
}
}
}
]
};
```
It is not possible to display empty labels when there is no data
### What does the proposed API look like?
Expect the label to have a configuration option to also call the formatter
display tag when the data is empty
