matplotlib.pyplot.yscale()函数

在Python中matplotlib.pyplot.yscale()

matplotlib.pyplot.yscale()函数在matplotlib库的pyplot模块中用于设置y轴刻度。

语法:matplotlib.pyplot.yscale(价值,* * kwargs)

参数:

value = { “linear”, “log”, “symlog”, “logit”, … }

这些是各种轴的比例应用。

**kwargs =不同的关键字参数被接受，取决于规模(matplotlib.scale.LinearScale, LogScale, SymmetricalLogScale, LogitScale)

示例1

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import time
%matplotlib inline
  
# Example 1
y = np.random.randn(50)
y = y[(y > 0) & (y < 1)]
y.sort()
x = np.arange(len(y))
  
# plot with various axes scales
plt.figure()
  
# linear
plt.subplot(221)
plt.plot(x, y)
plt.yscale('linear')
plt.title('linear')
plt.grid(True)
  
  
# log
plt.subplot(222)
plt.plot(x, y)
plt.yscale('log')
plt.title('log')
plt.grid(True)
  
  
plt.show()

输出:

import matplotlib.pyplot as plt

%matplotlib inline
  
# Example 2
# useful for `logit` scale
from matplotlib.ticker import NullFormatter
  
# Fixing random state for reproducibility

# make up some data in the
# interval ]0, 1[
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))
  
# plot with various axes scales
plt.figure()
  
# symmetric log
plt.subplot(221)
plt.plot(x, y - y.mean())
plt.yscale('symlog', linthreshy=0.01)
plt.title('symlog')
plt.grid(True)
  
# logit
plt.subplot(222)
plt.plot(x, y)
plt.yscale('logit')
plt.title('logit')
plt.grid(True)
  
plt.gca().yaxis.set_minor_formatter(NullFormatter())
  
# Adjust the subplot layout, because
# the logit one may take more space
# than usual, due to y-tick labels like "1 - 10^{-3}"
plt.subplots_adjust(top=0.80, bottom=0.03, 
                    left=0.15, right=0.92,
                    hspace=0.34,wspace=0.45)
  
plt.show()
