条形图：修复可视化

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 ()

我希望将x轴标记为“学生费率”和“教师费率”。我知道如何标记x轴，但我不知道如何更改1,1.2,1.2等。

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

我该怎么做才能解决这个问题？

Answer 1

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

你可以创建一个标签数组：

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

然后修改x刻度：

plt.xticks(x, labels)
