python 画图

画图时，全面变量的设置：

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
from pylab import mpl
import seaborn as sns
import data

mpl.rcParams['font.sans-serif'] = ['SimHei']
plt.rcParams['axes.unicode_minus'] = False
plt.figure(facecolor='snow')
sns.set_style("darkgrid", {"font.sans-serif": ['simhei', 'Droid Sans Fallback','Times New Roman']})
font_size = 12
font_family = "SimHei"
font_weight = "bold"
plt.rc("font", size=font_size, family=font_family, weight=font_weight)
#  my_font = fm.FontProperties(fname="C:\Windows\Fonts\simhei.ttf")
 
font2 = {'family' : 'Times New Roman',
'weight' : 'bold',
'size'   : 12,
}

# fig,ax=plt.subplots(figsize=(6.4,4.8), dpi=100)
fig,ax=plt.subplots(figsize=(6.4,4.8), dpi=100)
