将鼠标悬停在matplotlib烛台中以获取python [英] Mouse Hover in matplotlib candlestick for python

问题描述

我已经实现了这个示例:

I have implemented this example:

http://matplotlib.sourceforge.net/examples/pylab_examples/finance_demo.html?highlight = candlestick

我想为烛台实现鼠标悬停功能，这样我就可以在某个面板的弹出窗口或标签中看到烛台的开/高/低/收盘价.我跟着:

I would like to implement mouse hover features for the candlestick so that I can see the candlestick's open/high/low/close either in a popup or a label in a certain panel. I was following along with:

http://matplotlib.sourceforge.net/examples/event_handling/pick_event_demo.html

不幸的是，该功能:

candlestick(ax, quotes, width=0.6)

没有 picker = True 关键字.还有另一种方法来实现鼠标悬停功能吗?

does not have a picker=True keyword. Is there another way to implement the mouse hover feature?

推荐答案

我写了一个答案来处理鼠标悬停"事件

I wrote an answer to handle "mouse over" events here. That would be a good first point of call to find out how to do something similar.
