如何使用 matplotlib 在同一窗口中读取文件生成多个图 - Pyhton

Question

I have two .txt files and with them, I would like to plot the graphs corresponding to each file in the same window. I managed to plot only one. Using the code below:

import matplotlib.pyplot as plt

timecap = []
qtd = []

# f = open('dataset.txt', 'r')

for line in open('pkts_by_src.txt', 'r'):
    lines = [i for i in line.split(',')]
    timecap.append(lines[0])
    qtd.append(int(lines[1]))

plt.title("Capture")
plt.xlabel('time cap')
plt.ylabel('qtd')
plt.yticks(qtd)
plt.plot(timecap, qtd, marker='o', c='g')

plt.show()

The file is in this format:

22:40:16,2
22:40:20,1
22:40:20,2
22:40:23,1
22:40:23,4
22:40:23,6
22:40:23,8

Can you give me a tip? I'm a beginner in python

Answer 1

Try using the subplot function as shown. After calling it make your graph the repeat, at the end do show(), you can look at the matplotlib documentation for specific parameters.

plt.subplot(211)
for line in open('pkts_by_src.txt', 'r'):
    lines = [i for i in line.split(',')]
   ...

plt.subplot(212)
for line in open('wordlist2.txt', 'r'):
    lines = [i for i in line.split(',')]
   ...

plt.show()
