如何创建可以从中创建条形图的系列 [英] How do i create a series that I can create a bar chart from

问题描述

我有一个名字列表:['joe'，'brian'，'stephen']

I have a list of names: ['joe','brian','stephen']

我想在jupyter中创建一个条形图，以名称作为索引，并在条形图中显示每个名称中字母的数量.如何创建一个可以调用".plot(kind ='bar')"的系列，并获得所描述的条形图?

i would like to create a bar chart in jupyter with names as indexes and the bar showing the numbers of letters in each name. How do I create a series which I can call ".plot(kind='bar')" on and get a bar chart like described?

推荐答案

import numpy as np
import matplotlib.pyplot as plt

bars = ['joe','brian','stephen']
height = [len(m) for m in bars]
y_pos = np.arange(len(bars))
plt.bar(y_pos, height, color=(0.2, 0.4, 0.6, 0.6))
plt.xticks(y_pos, bars)
plt.show()
