Line plot

Line plot

import matplotlib.pyplot as plt

x= [1,4,7,9]

y= [0,5,10,15]

plt.plot(x,y)

plt.show()

import matplotlib.pyplot as plt

x= [1,4,7,9]

y= [0,5,10,15]

plt.plot(x,y,linewidth = 3.0,color = " maroon ",marker = "X")

plt.show()

customizing  the line chart  :

import numpy as np

import matplotlib.pyplot as plt

x= [10,20,30,50,60]

y =[20,40,60,80,100]

fig =plt.figure(figsize=(5,2))

plt. plot(x,y,linewidth = 1.0,linestyle = '-' , color = "red",alpha= 1.0,marker= "o")

plt. legend(["line"],loc = "best")

plt. grid(True)

plt.xlabel("x axis ")

plt.ylabel("y axis")

plt. show()

Adding two line chart 

import matplotlib.pyplot as plt

x= [1,4,7,9]

y= [0,5,10,15]

x1 = [10,20,30,40]

y1 = [0,10,20,30]

a = plt.subplot(2,2,1)

a.plot(x,y,linewidth = 0.5,marker = 'o')

b= plt.subplot(2,2,2)

b.plot(x1,y1,color = "red",linestyle = "--")

a. grid(True)

b. grid(True)

a. legend([" "])

b. legend(" ")

plt.show()
