Read text file and plot by using Pandas and matplotlib.pyplot in Python

Here is a sample code.

import pandas as pd
import matplotlib.pyplot as plt

filename = 'a.txt'

data = pd.read_csv(filename, sep='\t', header=None)
plt.plot(data[0],data[1])
plt.xlabel('Raman shift (cm-1)', size=14)
plt.ylabel('Intensity', size=14)
plt.xlim(1000,3000)
plt.savefig('Raman.png', transparent=True)
plt.show()
