event handlers are not typed

https://github.com/plotly/angular-plotly.js/blob/5201d97fc2e01e5533d08a921cd44e28265a9222/projects/plotly/src/lib/plotly.component.ts#L80

I was attempting to implement some drill down functionality in the charts in my dashboard. Unfortunately, when I bound a method in my component to the (plotlyClick) output, I noticed that the type of $event was void. But my component method typed the event as unknown anyway, and I console.log the event object, and there is a ton of information in there.

On this line: https://github.com/plotly/angular-plotly.js/blob/master/projects/plotly/src/lib/plotly.component.ts#L241

...I can see that the output indeed is emitting data, just like my logging indicated. Is there anyway we could get these outputs typed? I imagine that the type would be pretty broad due to the amount of different charts/maps out there. But TypeScript thinking that the output is void is probably worse then just not knowing what the event data looks like, but still acknowledging its existence.

projects/plotly/src/lib/plotly.component.ts の 80 行目付近にある output の宣言と、241 行目付近にある emission から始めます。plotlyClick output から emit されるイベント payload を追跡し、チャートデータに対して十分に広い、実用的な TypeScript 型を outputs に付与します。完了条件は、emitted data の表現を維持したまま、consumer がイベントを void として認識しなくなることです。
