I have something different from others!
It showed an error when I code"%matplotlib notebook".
And I search google, I found I haven’t installed the ipympl yet.
So I installed it and change the code to “%matplotlib widget”, it’s done!
here the line: https://github.com/matplotlib/ipympl
First
%matplotlib widget
from matplotlib import pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
Second
# Orion
x = [-0.41, 0.57, 0.07, 0.00, -0.29, -0.32,-0.50,-0.23, -0.23]
y = [4.12, 7.71, 2.36, 9.10, 13.35, 8.13, 7.19, 13.25,13.43]
z = [2.06, 0.84, 1.56, 2.07, 2.36, 1.72, 0.66, 1.25,1.38]
Third
I have a question.
Why I have to code"fig.add_subplot"
It “plt.add_subplot” doesn’t work?
Why? Is it because “add_subplot” is kind of attribute?
fig = plt.figure()
fig.add_subplot(1,1,1)
plt.scatter(x,y)
plt.show()
Fourth
fig_3d = plt.figure()
fig_3d.add_subplot(1,1,1,projection="3d")
constellation3d = plt.scatter(x,y,z,color="black")
plt.show
