Zoom and have cursor for a matplotlib plot within iPython

问题

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

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

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.

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

回答1:

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()
