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.

从 PlotlyComponent chart ref 以及 issue 中引用的 Plotly APIs 开始，包括 l2p、d2p 和 Fx.loneHover。确定该组件是否提供一种无需 event 即可获取数据点像素坐标的方式，并将完成标准定义为存在一种有文档记录或可工作的方式来以编程方式触发 hover。
