Two drawing interfaces - 1 Matlab style interface

MATLAB Style interface by plt Module supply ,plt Contains a series of drawing commands （ function ）, Name and MATLAB Almost the same .

# The import module / package 
import matplotlib.pyplot as plt
import numpy as np

# Generate the data 
x = np.linspace(0,10,200)

# Create a shape 
plt.figure()

# Create two subgraph templates 
# Create the first sub graph 
plt.subplot(2,1,1)
plt.plot(x,np.cos(x))# Drawing graphics 

# Create the 2 Subtext 
plt.subplot(2,1,2)
plt.plot(x,np.sin(x))# Drawing graphics 

plt.show()

It's used here 3 An order , Each one is very concise .

1. figure() function ： Create a blank graphic .
2. subplot ( rows , columns , subplot number ) function ： Create subgraphs , The first 1 Set the number of lines in the subgraph with three parameters , The first 2 Parameters set the number of subgraphs , The first 3 Parameter setting sub figure serial number .
3. plot (x , y ) function ： Drawing graphics , The first 1 The parameter is x Axis provides data , The first 2 The parameter is y Axis provides data .
