Graph drawing

graph.py

import termplotlib as tpl
import numpy as np

x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x) + x
fig = tpl.figure()
fig.plot(x, y, width=60, height=20)
fig.show()

Use csv

a.csv

1, 3
2, 1
3, 2.5
4, 8

graph.py

import pandas as pd
headers = ['x', 'y']
df = pd.read_csv('a.csv',names=headers)
#print(df)

import termplotlib as tpl
x = df['x']
y = df['y']
fig = tpl.figure()
fig.plot(x, y, width=60, height=20)
