中意外的必需参数“bottom”matplotlib.pyplot.barh()

Question

我在画一个简单的横条图。为了可读性，我想用 关键字参数，但在执行此操作时，遇到一个未记录的必需参数的错误。在

import pandas as pd
import matplotlib.pyplot as plt
plt.figure(figsize=(4,2))

# this example works
plt.barh([1, 1, 1], 
         [9.5, 8.5, 28.5], 
         [.3, .3, .3],
         [-2207, -2197, -2188])

# here I want to use keyword arguments for readability, according to 
# https://matplotlib.org/api/_as_gen/matplotlib.pyplot.barh.html?highlight=barh  
plt.barh(y=[1, 1, 1], 
         width= [9.5, 8.5, 28.5], 
         height = [.3, .3, .3],
         left = [-2207, -2197, -2188])

# But I get error:
#   File "<ipython-input-6-2f6ee5c89917>", line 4, in <module>
#   left = [-2207, -2197, -2188])

# TypeError: barh() missing 1 required positional argument: 'bottom'

documentation中没有“bottom”参数：
