python画图时设置分辨率和画布大小-plt.figure()

• plt.figure()

示例：

import numpy as np
import pandas as pd
import warnings
warnings.filterwarnings('ignore')
import matplotlib.pyplot as plt
import seaborn as sns

#读取示例数据
df = pd.read_csv(   'https://labfile.oss.aliyuncs.com/courses/1283/telecom_churn.csv')
#sns.countplot(x='State', hue='Churn', data=df)

#画分布图
sns.countplot(x=df['State'], hue=df['Churn'])

调整后：

# 分辨率参数-dpi，画布大小参数-figsize
plt.figure(dpi=300,figsize=(24,8))
# 改变文字大小参数-fontsize
plt.xticks(fontsize=10)

#画分布图
sns.countplot(x=df['State'], hue=df['Churn'])
