Pyplot自动对y值进行排序

Question

我对我最喜欢的节目的片段中所说的单词进行了频率分析。我正在绘制plot.barh（s1e1_y，s1e1_x），但是它是按单词而不是值进行排序的。的输出>>> s1e1_y 是

['know', 'go', 'now', 'here', 'gonna', 'can', 'them', 'think', 'come', 'time', 'got', 'elliot', 'talk', 'out', 'night', 'been', 'then', 'need', 'world', "what's"]

和 >>>s1e1_x

[42, 30, 26, 25, 24, 22, 20, 19, 19, 18, 18, 18, 17, 17, 15, 15, 14, 14, 13, 13]

当实际绘制绘图时，即使绘图列表未排序，图表的y轴刻度也会按字母顺序排序...

s1e1_wordlist = []

s1e1_count = []

for word, count in s1e01:

    if((word[:-1] in excluded_words) == False):

        s1e1_wordlist.append(word[:-1])

        s1e1_count.append(int(count))

s1e1_sorted = sorted(list(sorted(zip(s1e1_count, s1e1_wordlist))), 

reverse=True)

s1e1_20 = []

for i in range(0,20):

    s1e1_20.append(s1e1_sorted[i])

s1e1_x = []

s1e1_y = []

for count, word in s1e1_20:

    s1e1_x.append(word)

    s1e1_y.append(count)

plot.figure(1, figsize=(20,20))

plot.subplot(341)

plot.title('Season1 : Episode 1')

plot.tick_params(axis='y',labelsize=8)

plot.barh(s1e1_x, s1e1_y)

Answer 1

好的，您的示例中似乎有很多虚假代码，与您所描述的问题无关，但是假设您不希望y轴按字母顺序排序，则需要将两个列表压缩为一个数据框，然后按如下所示绘制数据框df = pd.DataFrame(list(zip(s1e1_y,s1e1_x))).set_index(1)df.plot.barh()
