JupyterNotebook 可视化技巧

import numpy as np
import pandas as pd
import seaborn as sns
from matplotlib import pyplot as plt

• 格子

  sns.set_style("whitegrid")
  

• svg显示
  deprecated

  %config InlineBackend.figure_format = 'svg' # 
  

  新方法：

  from IPython.display import set_matplotlib_formats
  set_matplotlib_formats('svg')
  

• svg保存

  plt.savefig('%s.pdf'%file, bbox_inches='tight')
  

• 中文

  plt.rcParams['font.sans-serif'] = ['SimHei']
  plt.rcParams['axes.unicode_minus'] = False
  

• 3D坐标系

  from mpl_toolkits.mplot3d import Axes3D
  fig = plt.figure()
  ax = Axes3D(fig)
  ax.scatter3D(xs,ys,zs,marker='.')
  

• 可交互的3D视图（由于某bug，所以%matplotlib notebook写两次）

  %matplotlib notebook
  %matplotlib notebook
  
  ax.scatter3D(xs,ys,zs,marker='.')
