以下报道 here我尝试创建一个带有重叠散点图的箱线图。

但是当我运行时:

In [27]: table1.t_in[table1.duration==6]
Out[27]:
counter
7 308.351304
9 305.354920
14 307.832732
15 332.097405
21 309.711144
22 308.227617
23 317.342377
24 306.140126
25 339.185127
27 336.411869
30 313.287353
Name: t_in, dtype: float64
In [28]: table1.t_in[table1.duration==7]
Out[28]:
counter
10 401.891105
11 384.290236
13 387.516037
17 369.366080
18 383.584934
19 357.466159
20 380.888071
26 399.989748
34 353.118944
Name: t_in, dtype: float64
In [29]: fig,ax=plt.subplots()
...:
...: for i in [6,7]:
...: y = table1.t_in[table1.duration==i]
...: # Add some random "jitter" to the x-axis
...: x = np.random.normal(i, 0.03, size=len(y))
...: ax.plot(x, y, 'r.', alpha=0.5)
...:
...: bp = table1.boxplot(column='t_in',by='duration',grid=False,ax=ax)

我得到:enter image description here

如果我只跳过最后一行,我会得到: enter image description here

我怎样才能像链接的问题一样绘图?

最佳答案

使用 ipython 笔记本。我尝试了matplotlib的boxplot-Methode。不能包含在 for 循环中。但希望它能有所帮助。

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
%matplotlib inline

# data
table1 = pd.DataFrame({"t_in":[308.351304, 305.354920, 307.832732,
332.097405, 309.711144, 308.227617,
317.342377, 306.140126, 339.185127,
336.411869, 313.287353, 401.891105,
384.290236, 387.516037, 369.366080,
383.584934, 357.466159, 380.888071,
399.989748, 353.118944]},
index=[7,9,14,15,21,22,23,24,25,27,30,
10,11,13,17,18,19,20,26,34])

table1["duration"] = np.where(table1["t_in"]<353, 6, 7)

# plotting
fig,ax = plt.subplots()
colors = ["red", "blue"]
for i in [6,7]:
y = table1.t_in[table1.duration==i]
# Add some random "jitter" to the x-axis
x = np.random.normal(i, 0.03, size=len(y))
ax.scatter(x, y, c=colors[i-6], alpha=0.5)

ax.boxplot([table1.t_in[table1.duration==6].values,table1.t_in[table1.duration==7].values], positions=[6,7])
plt.show()
