Accessing pixel coordinates of data without event

I'm trying to do something similar to the following forums where I'm trying to get the x, y coordinates of a data point in order to use the Fx.loneHover to programmatically trigger a hover event.

• https://community.plot.ly/t/how-to-customize-plotly-tooltip/332/21
• https://github.com/plotly/plotly.js/issues/1963

Any advice on how to achieve this? If I inspect the chart ref in the PlotlyComponent in does not have the function l2p or d2p anywhere within the object and I do not have an event handle to use to retrieve the x and y relative pixel locations.

從 PlotlyComponent chart ref 以及 issue 中引用的 Plotly APIs 開始，包括 l2p、d2p 和 Fx.loneHover。確認該元件是否提供一種不需要 event 即可取得資料點像素座標的方式，並將完成標準定義為存在一種有文件記錄或可運作的方式，以程式方式觸發 hover。
