**TITLE**
[Feature] legend.formatter function, can the parameters it receives be the
same as tooltip.formatter?
**BODY**
### What problem does this feature solve?
- I tried to combine the two features of theme and dataset. Define the
specified attributes in the dataset and use them in the formatter of some
components of the theme to achieve the purpose of personalizing the style and
convenient expansion. This method worked in the tooltip. Its formatter can
accept dataset-related attributes, but the parameters received by
legend.formatter are only name and cannot be expanded.
### What does the proposed API look like?
```javascript
{
legend: {
formatter: (params) => params.data.xxx
}
}
```
