我想让下面的箱线图中的 mustache 线更宽。
import pandas as pd
import numpy as np
import seaborn as sns
import matplotlib.pyplot as plt
data = pd.DataFrame({'Data': np.random.random(100), 'Type':['Category']*100})
fig, ax = plt.subplots()
# Plot boxplot setting the whiskers to the 5th and 95th percentiles
sns.boxplot(x='Type', y='Data', data=data, color = 'gray', whis = [5,95])
# Adjust boxplot and whisker line properties
for p, artist in enumerate(ax.artists):
artist.set_edgecolor('blue')
for q in range(p*6, p*6+6):
line = ax.lines[q]
line.set_color('pink')
我知道如何调整 mustache 颜色和线宽,但我一直无法弄清楚如何增加 mustache 的长度。我最接近的是尝试使用
line.set_xdata([q/60-0.5, q/60+0.5])
但我收到错误ValueError: shape mismatch: objects cannot be broadcast to a single shape
理想情况下,我希望 mustache 百分位线与盒子的宽度相同。我怎样才能做到这一点?
最佳答案
正如您所注意到的,每个框都绘制了 6 条线(因此是您的 p*6
索引)。
索引为 p*6+4
的行具有框的宽度(即框内的中线)。所以我们可以用它来设置其他线条的宽度。
您要更改的行具有索引 p*6+2
和 p*6+3
。
import pandas as pd
import numpy as np
import seaborn as sns
import matplotlib.pyplot as plt
data = pd.DataFrame({'Data': np.random.random(100), 'Type':['Category']*100})
fig, ax = plt.subplots()
# Plot boxplot setting the whiskers to the 5th and 95th percentiles
sns.boxplot(x='Type', y='Data', data=data, color = 'gray', whis = [5,95])
# Adjust boxplot and whisker line properties
for p, artist in enumerate(ax.artists):
artist.set_edgecolor('blue')
for q in range(p*6, p*6+6):
line = ax.lines[q]
line.set_color('pink')
ax.lines[p*6+2].set_xdata(ax.lines[p*6+4].get_xdata())
ax.lines[p*6+3].set_xdata(ax.lines[p*6+4].get_xdata())
这也适用于具有多个框的示例:
import pandas as pd
import numpy as np
import seaborn as sns
import matplotlib.pyplot as plt
sns.set(style="whitegrid")
tips = sns.load_dataset("tips")
ax = sns.boxplot(x="day", y="total_bill", data=tips)
# Adjust boxplot and whisker line properties
for p, artist in enumerate(ax.artists):
artist.set_edgecolor('blue')
for q in range(p*6, p*6+6):
line = ax.lines[q]
line.set_color('pink')
ax.lines[p*6+2].set_xdata(ax.lines[p*6+4].get_xdata())
ax.lines[p*6+3].set_xdata(ax.lines[p*6+4].get_xdata())
