Pandas Dataframe：area plot stacked ='false'not working

Question

即使我通过设置参数 stacked ='false'明确停用堆叠，我仍然会堆积一个区域图。

以下是一些示例代码：

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from datetime import datetime as dt

# Generate sample data
sample_data = np.random.rand(24*365, 5)
df = pd.DataFrame(sample_data,
                  index=pd.date_range('1/1/2015 00:00',
                                      periods=len(sample_data), freq='H'))

# Select date range to plot
date_from = dt(2015, 12, 22, 12, 0)
date_to = dt(2015, 12, 22, 23, 0)
df = df.loc[date_from:date_to]

# Plotting
df.plot(kind='line', colormap='Blues')
# Place legend topright
[ax.legend(loc=1) for ax in plt.gcf().axes]
df.plot(kind='bar', stacked='true', colormap='Greens')
# Place legend topright
[ax.legend(loc=1) for ax in plt.gcf().axes]
df.plot(kind='barh', stacked='true', colormap='Oranges')
# Place legend topright
[ax.legend(loc=1) for ax in plt.gcf().axes]

# This one doesn't work as explained in
# http://pandas.pydata.org/pandas-docs/stable/visualization.html
df.plot(kind='area', stacked='false', alpha=0.5, colormap='Reds')
# Place legend topright
[ax.legend(loc=1) for ax in plt.gcf().axes]

区域图在我的机器上看起来像这样：

我有两个问题：

1.。）如何修复区域图以使其不堆叠？

2。）在每个情节之后，有没有办法摆脱重复的“[ax.legend（loc = 1）for ax in plt.gcf（）。axes]”？

提前致谢！

Answer 1

设置 stacked = False 而不是'false'为我解决了第一个问题！
