Matplotlib Is a library in Python and it is a numerical – mathematical extension for the NumPy library. Pyplot Is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.
matplotlib.pyplot.yscale() in Python
The matplotlib.pyplot.yscale() function in pyplot module of matplotlib library is used to set the y-axis scale.
Syntax: matplotlib.pyplot.yscale(value, **kwargs)
Parameters:
value = { “linear”, “log”, “symlog”, “logit”, … }
These are various axis scale to apply.
**kwargs = Different keyword arguments are accepted, depending on the scale (matplotlib.scale.LinearScale, LogScale, SymmetricalLogScale, LogitScale)
Example 1:
Python3
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import time
% matplotlib inline
y = np.random.randn( 50 )
y = y[(y > 0 ) & (y < 1 )]
y.sort()
x = np.arange( len (y))
plt.figure()
plt.subplot( 221 )
plt.plot(x, y)
plt.yscale( 'linear' )
plt.title( 'linear' )
plt.grid( True )
plt.subplot( 222 )
plt.plot(x, y)
plt.yscale( 'log' )
plt.title( 'log' )
plt.grid( True )
plt.show()
|
Output:
yscale plots for linear and log
Example 2:
Python3
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import time
% matplotlib inline
from matplotlib.ticker import NullFormatter
np.random.seed( 100 )
y = np.random.normal(loc = 0.5 ,
scale = 0.4 , size = 1000 )
y = y[(y > 0 ) & (y < 1 )]
y.sort()
x = np.arange( len (y))
plt.figure()
plt.subplot( 221 )
plt.plot(x, y - y.mean())
plt.yscale( 'symlog' , linthreshy = 0.01 )
plt.title( 'symlog' )
plt.grid( True )
plt.subplot( 222 )
plt.plot(x, y)
plt.yscale( 'logit' )
plt.title( 'logit' )
plt.grid( True )
plt.gca().yaxis.set_minor_formatter(NullFormatter())
plt.subplots_adjust(top = 0.80 , bottom = 0.03 ,
left = 0.15 , right = 0.92 ,
hspace = 0.34 ,wspace = 0.45 )
plt.show()
|
Output:
yscale plots for symlog and logit
