如何在 Google Colab 交互式中制作 matplotlib 图

use*_*817 7 python 3d matplotlib google-colaboratory

我正在使用 python 和 matplotlib,我正在尝试在 Google Colab 中创建一个交互式绘图。我可以制作情节,但它是静态的。我当前的代码如下:

%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_di = [1/sp for sp in sta_pa]

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

plt.show()

您应该删除%matplotlib inline,这使情节静态。%matplotlib notebook您之前放置的魔术命令是交互式绘图所需的命令。

编辑: Colab 仅支持%matplotlib inline请参见此处,因此无法获得交互式 matplotlib 绘图。但是,如果您切换到另一个环境(Jupyter 或 JupyterLab),请确保使用%matplotlib notebook. 另一方面,交互式情节似乎有效:Google Colab 中的交互式 matplotlib 数字

  • 看来 Colab 目前只支持 `%matplotlib inline`:https://github.com/googlecolab/colabtools/issues/616#issuecomment-506829877 (2认同)
