在一张图中绘制多个 pandas 数据框

我创建了6个不同的数据框，以消除其原始数据框的异常值.现在，我试图在同一图形上绘制所有消除异常值的数据框.

I have created 6 different dataframes that eliminate the outliers of their own original data frames. Now, I'm trying to plot all of the dataframes that eliminate the outliers on the same graph.

这是我的代码，它消除了每个数据帧中的异常值:

This is my code that eliminates the outliers in each data frame:

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
plt.style.use("ggplot")

#---Original DataFrame
x = (g[0].time[:27236])
y = (g[0].data.f[:27236])
df = pd.DataFrame({'Time': x, 'Data': y})

#----Removes the outliers in a given DataFrame and plots a graph
newdf = df.copy()
newdf = df[~df.groupby('Data').transform( lambda x: abs(x-x.mean()) > 1.96*x.std()).values]
#newdf.plot('Time', 'Data')

#---Original DataFrame
x = (q[0].time[:47374])
y = (q[0].data.f[:47374])
df = pd.DataFrame({'Time': x, 'Data': y})

#----Removes the outliers in a given DataFrame and plots a graph
newdf = df.copy()
newdf2 = df[~df.groupby('Data').transform( lambda x: abs(x-x.mean()) > 1.96*x.std()).values]
#newdf2.plot('Time', 'Data')

#---Original DataFrame
x = (w[0].time[:25504])
y = (w[0].data.f[:25504])
df = pd.DataFrame({'Time': x, 'Data': y})

#----Removes the outliers in a given DataFrame and plots a graph
newdf = df.copy()
newdf3 = df[~df.groupby('Data').transform( lambda x: abs(x-x.mean()) > 1.96*x.std()).values]
#newdf3.plot('Time', 'Data')

#---Original DataFrame
x = (e[0].time[:47172])
y = (e[0].data.f[:47172])
df = pd.DataFrame({'Time': x, 'Data': y})

#----Removes the outliers in a given DataFrame and plots a graph
newdf = df.copy()
newdf4 = df[~df.groupby('Data').transform( lambda x: abs(x-x.mean()) > 1.96*x.std()).values]
#newdf4.plot('Time', 'Data')

#---Original DataFrame
x = (r[0].time[:21317])
y = (r[0].data.f[:21317])
df = pd.DataFrame({'Time': x, 'Data': y})

#----Removes the outliers in a given DataFrame and plots a graph
newdf = df.copy()
newdf5 = df[~df.groupby('Data').transform( lambda x: abs(x-x.mean()) > 1.96*x.std()).values]
#newdf5.plot('Time', 'Data')

#---Original DataFrame
x = (t[0].time[:47211])
y = (t[0].data.f[:47211])
df = pd.DataFrame({'Time': x, 'Data': y})

#----Removes the outliers in a given DataFrame and plots a graph
newdf = df.copy()
newdf6 = df[~df.groupby('Data').transform( lambda x: abs(x-x.mean()) > 1.96*x.std()).values]
#newdf6.plot('Time', 'Data')

如果我删除注释newdf.plot()，我将能够分别绘制所有图形，但是我希望它们全部集中在一个图形上.

If I remove the comment newdf.plot() I will be able to plot all of the graphs separately but I want them all on one graph.

是的，我已经阅读了 http://matplotlib.org/examples/pylab_examples /subplots_demo.html 但是该链接没有任何示例在一个图表中包含多个图表.

And yes, I've already read over http://matplotlib.org/examples/pylab_examples/subplots_demo.html but that link doesn't have any examples with multiple plots in one chart.

我还阅读了以下内容: http://pandas-docs. github.io/pandas-docs-travis/visualization.html 确实提供了一些很好的信息，但是在一个图中包含多个图的示例使用相同的数据框.我有6个单独的数据框. 我想到了解决我的问题的一种方法，就是将所有数据框都写入相同的excel文件，然后从excel中绘制它们，但这似乎过多了，我不需要将这些数据保存到excel文件中.

I have also read this: http://pandas-docs.github.io/pandas-docs-travis/visualization.html which has some really great information but the examples that have multiple plots in one graph use the same data frame. I have 6 separate dataframes. I've thought of one solution to my problem would be to write all of the dataframes to the same excel file then plot them from excel, but that seems excessive and I don't need this data to be saved to an excel file.

我的问题是这样的: 如何在同一张图中绘制多个熊猫数据框.

My question is this: How can I plot multiple pandas dataframes in the same graph.
