本节(31)主要介绍: 用python画柱状图,带errorbar,以及分组展示
import seaborn as sns
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
# Load an example dataset
# tips = sns.load_dataset("tips")
tips = pd.read_csv('C:/Users/RONG/Desktop/PythonBasic/tips.csv')
print(tips.head())
plt.figure()
sns.barplot(x = 'day', y = 'total_bill', data = tips)
plt.show()
Fig1.png
plt.figure()
sns.barplot(x = 'day', y = 'total_bill', hue = 'sex', data = tips \
,order = ['Thur','Fri','Sat','Sun'] \
,estimator = np.median \
,palette = 'Blues_d' \
,capsize = .1 \
)
plt.show()

plt.figure()
sns.barplot(x = 'tip', y = 'size', data = tips, orient = 'h')
plt.show()
