您只需调用.plot()，就像调用一个正常的线条图一样。
对您所提及的示例做了轻微的修改：
import numpy as np
import matplotlib.pyplot as plt
N = 5
menMeans = (20, 35, 30, 35, 27)
womenMeans = (25, 32, 34, 20, 25)
menStd = (2, 3, 4, 1, 2)
womenStd = (3, 5, 2, 3, 3)
ind = np.arange(N) # the x locations for the groups
width = 0.35 # the width of the bars: can also be len(x) sequence
fig, ax = plt.subplots()
ax.bar(ind, menMeans, width, color='r', yerr=womenStd,
align='center', label='Woman')
ax.bar(ind, womenMeans, width, color='y', yerr=menStd,
bottom=menMeans, align='center', label='Men')
ax.set_ylabel('Scores')
ax.set_title('Scores by group and gender')
ax.set_xticks(ind)
ax.set_xticklabels(('G1', 'G2', 'G3', 'G4', 'G5'))
ax.set_yticks(np.arange(0,81,10))
ax.plot(np.random.randint(20,50,5), 'o-', lw=2, color='k', label='Line')
ax.legend()
如果您想要一个单独的缩放，请在Matplotlib的示例页面上查看比例尺示例，这将在相同的轴(比例)上绘制这条线。
