Python 从matplotlib AXESSUBBLOT获取值

我想从方法返回的

matplotlib.axes.AxesSubplot

中获取值。 有没有办法做到这一点？我在列表中找不到该属性

import pandas as pd
import matplotlib.pyplot as plt

serie = pd.Series([0.0,950.0,-70.0,812.0,0.0,-90.0,0.0,0.0,-90.0,0.0,-64.0,208.0,0.0,-90.0,0.0,-80.0,0.0,0.0,-80.0,-48.0,840.0,-100.0,190.0,130.0,-100.0,-100.0,0.0,-50.0,0.0,-100.0,-100.0,0.0,-90.0,0.0,-90.0,-90.0,63.0,-90.0,0.0,0.0,-90.0,-80.0,0.0,])
hist = serie.hist()
# I want to get values of hist variable.

---

我知道我可以使用

np.histogram

获得直方图值，但我想使用pandas hist方法。

正如

xnx

在评论中指出的那样，这不像使用

plt.hist

那么容易访问。但是，如果您确实想使用pandas

hist

函数，则可以从调用

serie.hist

时添加到

hist

axesssubplot

的

补丁中获取此信息

下面是一个函数，用于在面片中循环，并返回面元边缘和直方图计数：

import pandas as pd
import matplotlib.pyplot as plt

serie = pd.Series([0.0,950.0,-70.0,812.0,0.0,-90.0,0.0,0.0,-90.0,0.0,-64.0,208.0,0.0,-90.0,0.0,-80.0,0.0,0.0,-80.0,-48.0,840.0,-100.0,190.0,130.0,-100.0,-100.0,0.0,-50.0,0.0,-100.0,-100.0,0.0,-90.0,0.0,-90.0,-90.0,63.0,-90.0,0.0,0.0,-90.0,-80.0,0.0,])
hist = serie.hist()

def get_hist(ax):
    n,bins = [],[]
    for rect in ax.patches:
        ((x0, y0), (x1, y1)) = rect.get_bbox().get_points()
        n.append(y1-y0)
        bins.append(x0) # left edge of each bin
    bins.append(x1) # also get right edge of last bin

    return n,bins

n, bins = get_hist(hist)

print n
print bins

plt.show()

下面是
n
和
bin
的输出：

[36.0, 1.0, 3.0, 0.0, 0.0, 0.0, 0.0, 0.0, 2.0, 1.0]                          # n
[-100.0, 5.0, 110.0, 215.0, 320.0, 425.0, 530.0, 635.0, 740.0, 845.0, 950.0] # bins

下面是要检查的直方图：

我不确定这是否可行：熊猫似乎会扔掉matplotlib返回给它的装箱数据、装箱边和面片对象。为什么不直接用
plt.hist
绘图？
