Python 绘制 3D 数据

一、XYZ数据: points.csv

     

1.1,1.2,1.3
2.1,2.2,2.3
3.1,3.2,3.3
4.1,4.2,4.3

一、Python绘制脚本: plot_3D.py

from    mpl_toolkits.mplot3d import Axes3D

import  matplotlib.pyplot as plt
import  pandas  as  pd



points = pd.read_csv('points.csv')
frame = pd.DataFrame(points)

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

x = frame.iloc[:,0]
y = frame.iloc[:,1]
z = frame.iloc[:,2]

#  x   y   z  
# 1.1,1.2,1.3
# 2.1,2.2,2.3
# 3.1,3.2,3.3
# 4.1,4.2,4.3

ax.scatter(x, y, z, c='r', marker='o')

plt.show()
