使用matplotlib绘制直方图或散点图

Question

import matplotlib.pyplot as plt
import education
list_of_record = education.get_all_states

virginia_education = education.get_state('Virginia')
enrollment = virginia_education ["enrollment"]
students = enrollment ["students"]
race = students ["race"]

asian = race["asian"]
biracial = race["biracial"]
hispanic = race ["hispanic"]
white = race ["white"]
black = race["black"]
native_american = race["native american"]

all_race = [asian, biracial, hispanic, white, black, native_american]

plt.hist (all_race)
plt.show ()

当前直方图图片：

我想修改它，使其显示所有种族的名称。x轴和y轴上的数字是错误的，我不确定如何修复。

一些数据：

如果您能在问题的代码中包含（小）一部分实际数据，那将是非常好的。这样，试图帮助您的人可以立即运行您的示例，进行调试，并验证他们的潜在解决方案。 - Lukas Graf

Answer 1

我认为你想要使用的是条形图。直方图用于检查数值数据的分布。以下是我实现它的方式：

import matplotlib.pyplot as plt
import education
list_of_record = education.get_all_states

virginia_education = education.get_state('Virginia')
enrollment = virginia_education["enrollment"]
students = enrollment["students"]
race = students["race"]

x = range(len(race)) # x-axis list
label = [] # x-labels list
y = [] # y-values list
for race, value in race.items():
    label.append(race) # add race to x-labels list
    y.append(value) # add value to y-values list

plt.bar(x,y,color='indianred',tick_label=label,align='center')
plt.show()
