缩放并在iPython中使用光标绘制matplotlib图 [英] Zoom and have cursor for a matplotlib plot within iPython

问题描述

在Google协作范围内，我无法使用matplotlib. use(TkAgg).

Within Google-colaboratory, I cannot use matplotlib. use(TkAgg).

它为我提供的可能性非常有帮助:

The possibility that it offers to me is though very helpful:

我可以交互放大绘图，还可以得到一个光标，向我显示鼠标悬停在其中的x和y的当前值.

I can zoom in my plot interactively and also get a cursor that shows me the present values of x and y where my mouse is hovering over.

iPython/Jupyter中是否存在具有相似功能的相似内容?

Is there anything similar within iPython / Jupyter that has a similar functionality?

推荐答案

有了这些代码段，缩放和鼠标X/Y光标悬停在Google Colab中都可以使用:

With these snippet, both zooming and the hovered mouse x/y cursor works in google colab:

!pip install mpld3
!pip install "git+https://github.com/javadba/mpld3@display_fix"
import mpld3
from mpld3 import plugins
fig, ax = plt.subplots()

ax.plot(a, "-o", markersize=2)
plugins.connect(fig, plugins.MousePosition(fontsize=14))

mpld3.display()
