Get values ​​from matplotlib AxesSubplot

Question

I would like to get values ​​from matplotlib.axes.AxesSubplotthat are returned from the pandas.Series.hist method . Is there any way to do this? I could not find the attribute in the list.

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.

I know I can get the histogram values ​​with np.histogram, but I want to use the pandas hist method.

xnx, , plt.hist. , pandas hist, patches, hist AxesSubplot, serie.hist.

:

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()

n bins:

[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
