画正太分布直方图（matplotlib）

# draw hist 


from matplotlib import pyplot as plt
from random import gauss
#from matplotlib import rc
from matplotlib import font_manager


#font = {‘family‘:‘方正粗黑宋简体‘,‘weight‘:‘bold‘}
#rc(‘font‘,**font) #设置字体

myfont = font_manager.FontProperties(fname = r"C:\\Windows\\Fonts\\simsun.ttc")
lis1 = []

# 用random产生正太分布数
def creatNumbers():
    for i in range(100):
        lis1.append(gauss(10,3))

creatNumbers()
plt.figure(figsize = (20,8),dpi = 80)
plt.hist(lis1,7) # 7 is the group
plt.xticks()
plt.xlabel(u"数据",fontproperties= myfont)
plt.ylabel(u"密度",fontproperties = myfont)
plt.title("图表",fontproperties=myfont)
#plt.legend()

plt.grid()
plt.show()

# conclusion  对于字体的设置，xlabel ylabel xticks yticks tittle 中并没有fontproperties参数 ,但是它确实有作用
