绘制python中计数器给出的最常见单词

Question

最常用的单词列表输出如下：

[('电影', 904), ('电影', 561), ('one', 379), ('like', 292)]

我想要一个根据数字对每个单词使用 matplotlib 的图形

请帮我

Answer 1

这是使用条形图快速采用此示例的一种方式。

#!/usr/bin/env python
# a bar plot with errorbars
import numpy as np
import matplotlib.pyplot as plt


data = [('film', 904), ('movie', 561), ('one', 379), ('like', 292)]
names, values = zip(*data)  # @comment by Matthias
# names = [x[0] for x in data]  # These two lines are equivalent to the the zip-command.
# values = [x[1] for x in data] # These two lines are equivalent to the the zip-command.

ind = np.arange(len(data))  # the x locations for the groups
width = 0.35       # the width of the bars

fig, ax = plt.subplots()
rects1 = ax.bar(ind, values, width, color='r')

# add some text for labels, title and axes ticks
ax.set_ylabel('Count')
ax.set_xticks(ind+width/2.)
ax.set_xticklabels(names)



def autolabel(rects):
    # attach some text labels
    for rect in rects:
        height = rect.get_height()
        ax.text(rect.get_x() + rect.get_width()/2., 1.05*height,
                '%d' % int(height),
                ha='center', va='bottom')

autolabel(rects1)

plt.show()
