条形图：固定可视化

Question

import matplotlib.pyplot as plt 
import education 
list_of_record = education.get_all_states() 
virginia_education = education.get_state('Virginia') 

attendance = virginia_education["attendance"] 

if "attendance" in virginia_education: 
    student_rate = attendance ["average student rate"] 
    teacher_rate = attendance ["average teacher rate"] 

rates = [student_rate, teacher_rate] 

x = rates 

plt.bar (1,student_rate) 
plt.bar (2,teacher_rate) 
plt.title ('Average Student Rate Attendence vs. Average Teacher Rate Attendence in Virginia') 
plt.show() 

我想x轴只被标记为“学生价”和“老师率”。我知道如何标记x轴，但我不知道如何改变1，1.2，1.2等

plt.bar (1,student_rate) 
plt.bar (2,teacher_rate) 

我怎么改解决这一问题？

Answer 1

据matplotlib网站： http://matplotlib.org/examples/ticks_and_spines/ticklabels_demo_rotation.html

您可以创建一个标签数组：

labels = ["student rate", "teacher rate"] 

然后修改X蜱：

plt.xticks(x, labels)
