列表中元素出现频率的图表

  • 772

请告诉我，是否可以绘制列表中元素出现频率的图表？

list_1 = [(1, 4), (1,), (1, 0), (1, 0), (3, 1, 0), (1, 0), (1, 0), (3, 2, 0), (2, 0), (2, 0), (10,), (3, 2, 0), (2, 0)]
c2 = Counter(list_1)
print(c2)

结论：

Counter({(1, 0): 4, (2, 0): 3, (3, 2, 0): 2, (1, 4): 1, (1,): 1, (3, 1, 0): 1, (10,): 1})
python matplotlib

    例如，您可以像这样：

    import matplotlib.pyplot as plt
from collections import Counter

list_1 = [(1, 4), (1,), (1, 0), (1, 0), (3, 1, 0), (1, 0), (1, 0), (3, 2, 0), (2, 0), (2, 0), (10,), (3, 2, 0), (2, 0)]
c2 = Counter(list_1)
fig, ax = plt.subplots()
x = list(range(len(c2)))

patches = ax.bar(data = c2, x = x, height=c2.values())
ax.bar_label(patches)
ax.set_xticks(x)
ax.set_xticklabels(c2.keys())
plt.show()

  2. 作为一种选择——通过Seaborn，他也有自己的计数方法。但是他不想取元组，所以他不得不把它们变成字符串：

    import seaborn as sns

list_1 = [(1, 4), (1,), (1, 0), (1, 0), (3, 1, 0), (1, 0), (1, 0), (3, 2, 0), (2, 0), (2, 0), (10,), (3, 2, 0), (2, 0)]

sns.countplot(y=list(map(str,list_1)))
