如何在 Google Colab 交互式中制作 matplotlib 图

Question

I am using python and matplotlib and I am trying to create an interactive plot in Google Colab. I can produce the plot but it is static. My current code is below:

%matplotlib notebook
%config InlineBackend.figure_format = 'retina'
from __future__ import print_function, division
import sys
import numpy as np
import astropy.units as u
import matplotlib.pyplot as plt
import os
%matplotlib inline
import json
import glob
import shutil
import math
from mpl_toolkits import mplot3d

fig = plt.figure(figsize=(15, 15))
ax = fig.add_subplot(111, projection='3d')

p_r = 299.9032078
p_de = 20.80420061
p_di = 1.5

ax.scatter(p_di,p_r,p_de, s=200, color='b',marker='o')

sta_r = [297.9021920849609,295.904451838485,295.9023343973089,297.90309565270053,296.90333856407784]
sta_de = [20.844424295419174,20.81360810319505,20.723442484679984,20.824023603726815,20.70437024345076]
sta_pa = [-0.5158962093235283,0.7968902494174,0.5119758027825232,-0.6155926470014295,1.2453997167305746]
sta_di = [1/sp for sp in sta_pa]

ax.scatter(sta_di,sta_r,sta_de, s=200, color='darkorange',marker='o')

plt.show()

Answer 1

You should remove %matplotlib inline , which makes the plot static. The %matplotlib notebook magic command you put earlier is the one you need for interactive plots.

Edit: Colab is only supporting %matplotlib inline , see here , and thus there is no way to get interactive matplotlib plots . Yet, if you switch to another environment ( Jupyter or JupyterLab ), make sure to use %matplotlib notebook . On the other side, interactive plotly seems to work: Interactive matplotlib figures in Google Colab

Answer 2

我认为 google collab 的交互模式仍然存在问题，因此最好为此目的使用 plotly(!pip install plotly)
