要更改按boxplot分组的熊猫中的群组标题,可以使用Matplotlib库中的方法来实现。具体步骤如下:
import pandas as pd
import matplotlib.pyplot as plt
data = {'Group': ['A', 'A', 'B', 'B', 'C', 'C'],
'Value': [1, 2, 3, 4, 5, 6]}
df = pd.DataFrame(data)
boxplot = df.boxplot(column='Value', by='Group')
group_labels = [group.get_text() for group in boxplot.get_xticklabels()]
new_group_labels = ['Group 1', 'Group 2', 'Group 3']
boxplot.set_xticklabels(new_group_labels)
plt.xlabel('Group')
plt.ylabel('Value')
plt.title('Boxplot')
plt.show()
完整的代码如下所示:
import pandas as pd
import matplotlib.pyplot as plt
data = {'Group': ['A', 'A', 'B', 'B', 'C', 'C'],
'Value': [1, 2, 3, 4, 5, 6]}
df = pd.DataFrame(data)
boxplot = df.boxplot(column='Value', by='Group')
group_labels = [group.get_text() for group in boxplot.get_xticklabels()]
new_group_labels = ['Group 1', 'Group 2', 'Group 3']
boxplot.set_xticklabels(new_group_labels)
plt.xlabel('Group')
plt.ylabel('Value')
plt.title('Boxplot')
plt.show()
这样就可以更改按boxplot分组的熊猫中的群组标题了。
