How does mplfinance support pick_event?
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?
I don't know much about "picking", but it seems to me that mplfinance may need changes in order to support picking.
I will try to make time, later this week, to to read through the picking tutorial and see if I can think of any way you can do it without the need to change mplfinance, or if I can think of an easy way to support picking in mpf.plot().
@DanielGoldfarb ： Thank you very much!
I have tested in detail that mplfinance supports common mouse events, such as figure_ enter_ event、figure_ leave_ event、axes_ enter_ event、axes_ leave_ event、button_ press_ Event. These events do not require plot to pass parameters.
But pick_ Event needs to pass in picker in plot, so it is not supported!
Looking forward to your good news!
It seems to me that mpf.plot() and mpf.make_addplot() will need to accept picker= as a kwarg, and then pass that picker on to the calls that they make to create the Artist objects on the plot.
If you are familiar with the fork and clone workflow you are welcome to try making this enhancement yourself.
I like the idea of supporting object picking in mpflinance, but I do not expect to have time to work on it for at least 3 months.
Thank you for your guidance! I'm not familiar with the workflow of fork and clone. Try it while learning!
Happy work!
