matplotlib 設置標題 xy標題等

 

import matplotlib.pyplot as plt
import matplotlib as mpl

baseclass=[1,2,3,4]
name = ['class1','class2','class3','class4']
scores = [67,79,89,50]
plt.title("title") # 圖形標題
plt.xlabel("x labal") # x軸名稱
plt.ylabel("y label") # y 軸名稱 
plt.xticks(baseclass,name) # x軸替換為名字
plt.bar(baseclass,scores)

#設置每個軸的值
for i in range(0,len(baseclass)):
    print(i)
    plt.text(baseclass[i],scores[i]+1,scores[i])
plt.show()

 結果如下
