Saya memiliki kerangka data, tetapi semua string diduplikasi dan ketika saya mencoba mencetak grafik, itu berisi kolom duplikat. Saya mencoba menghapusnya, tetapi grafik saya salah dicetak. CSV saya di sini.

Anda dapat melihat bahwa nama situs web terbalik. Saya mencoba mengurutkannya berdasarkan pair of websites dengan saya punya KeyError. Saya menggunakan kode
df = pd.read_csv("avito_trend.csv", parse_dates=[2])
def f(df):
dfs = []
for x in [list(x) for x in itertools.combinations(df['address'].unique(), 2)]:
c1 = df.loc[df['address'].isin([x[0]]), 'ID']
c2 = df.loc[df['address'].isin([x[1]]), 'ID']
c = pd.Series(list(set(c1).intersection(set(c2))))
#add inverted intersection c2 vs c1
c_invert = pd.Series(list(set(c2).intersection(set(c1))))
dfs.append(pd.DataFrame({'common users':len(c), 'pair of websites':' and '.join(x)}, index=[0]))
#swap values in x
x[1],x[0] = x[0],x[1]
dfs.append(pd.DataFrame({'common users':len(c_invert), 'pair of websites':' and '.join(x)}, index=[0]))
return pd.concat(dfs)
common_users = df.groupby([df['used_at'].dt.year]).apply(f).reset_index(drop=True, level=1).reset_index()
graph_by_common_users = common_users.pivot(index='pair of websites', columns='used_at', values='common users')
#sort by column 2014
graph_by_common_users = graph_by_common_users.sort_values(2014, ascending=False)
ax = graph_by_common_users.plot(kind='barh', width=0.5, figsize=(10,20))
[label.set_rotation(25) for label in ax.get_xticklabels()]
rects = ax.patches
labels = [int(round(graph_by_common_users.loc[i, y])) for y in graph_by_common_users.columns.tolist() for i in graph_by_common_users.index]
for rect, label in zip(rects, labels):
height = rect.get_height()
ax.text(rect.get_width() + 3, rect.get_y() + rect.get_height(), label, fontsize=8)
plt.show()
Grafik saya terlihat seperti:
rects = ax1.patches labels = ["%d" % i for i in time['time online'].round()] for rect, label in zip(rects, labels): print rect, label height = rect.get_height() ax1.text(rect.get_x() + rect.get_width()/2, height + 5, label, ha='center', va='bottom')Saya menjelaskan masalah saya di pertanyaan - person ldevyataykina schedule 20.03.2016
