Description
Because just learned MPL, MPF, finally understand what you want!
I want to find out other relevant data when the user clicks a bar after MPF draws the K-line graph. The key is to **pick_event.**
I checked your help and all the cases, and the chart is generated by "plot". But picker is not supported in "plot"!
**My question now is:**
**How to support “picker” in mplfinance?
Can you provide an example?**

Research direction
Start with the mplfinance plot entry point and the Matplotlib pick_event mechanism described in the issue. Reproduce a K-line chart, determine how bar artists are created, and establish whether picker support requires an API change or only an example; done means users can click a bar and retrieve relevant chart data.
