sthenault opened a new issue #14277:
URL: https://github.com/apache/echarts/issues/14277
### What problem does this feature solve?
would allow to define callback formatter with properly typed arguments: for
now I have to type ``params`` to ``any``, loosing typing within the formatter
function. For instance:
tooltip.formatter = (params: any) => {
// access to whatever in params is allowed
...
return content;
};
### What does the proposed API look like?
As I get it, ``params`` is expected to be of ``FormatterParams`` type, so
exporting in within echarts.d.ts would allow something along the line of :
import {FormatterParams} from "echarts";
...
tooltip.formatter = (params: FormatterParams) => {
// compilation error on access to something to defined in
FormatterParams
return content;
};
