Matplotlib: Matplotlib Line

• Linestyle 

If you want to change the style of the line, you can use ls.

 

Example 

import  matplotlib.pyplot as plt
import numpy as np 
ypoints = np.array ([2,6,7,0]) 

plt.plot(ypoints, ls = 'dotted')
plt.show()

 

• Shorter Syntax 

• linestyle can be written as ls.
• dotted can be written as :.
• dashed can be written as --.

 

• Line Styles 

Style	Or
'solid' (default)	'-'
'dotted'	':'
'dashed'	'--'
'dashdot'	'-.'
'None'	'' or ' '

 

 

• Line Color 

You can use argument c to set the color of the line. 

 

Example 

import matplotlib.pyplot as plt 
import numpy as np 

ypoints = np.array ([2,3,6,9]) 

plt.plot(ypoints, color = 'r') 

plt.show()

• Line Width 

We can also adjust the width of the line by using lw.

import matplotlib.pyplot as plt 
import numpy as np 

y =([3, 4, 5, 7]) 

plt.plot(y, lw = '20')
plt.show()

• Multiple Lines 

You can plot as many lines as you like by simply adding more plt.plot() functions. 

import matplotlib.pyplot as plt 
import numpy as np 

y1 = np.array ([1, 3, 5, 9])
y2 = np.array([6, 2, 7, 11])

plt.plot(y1)
plt.plot(y2)

plt.show()
