Seaborn条形图与折线图重叠

Question

我有以下数据框：

    date        Total1          Total2
0   3/24/2020   133731.9147     133731.9147
1   3/25/2020   141071.6383     274803.5529
2   3/26/2020   -64629.74024    210173.8127
3   3/27/2020   647.5360108     210821.3487

df.info（）是：

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 4 entries, 0 to 3
Data columns (total 3 columns):
date      4 non-null object
Total1     4 non-null float64
Total2    4 non-null float64
dtypes: float64(2), object(1)
memory usage: 168.0+ bytes

total2是total1的累积总数。我想制作一个条形图total1并将其与折线图total2重叠。

ax = sns.barplot(x="date",y="NetPL",data=gby)
ax.set_xticklabels(ax.get_xticklabels(), rotation=45)

这就是我当前用于条形图的内容。

我将日期转换为datetime后尝试了此操作

plt.style.use('ggplot')
ax =sns.barplot(x="date", y="Total1", data=df)
ax.set_xticklabels(ax.get_xticklabels(), rotation=45)

# add lineplot
sns.lineplot(x='date', y='Total2', data=df, marker='o')
plt.show()

Answer 1

date 未转换为日期时间格式

plt.style.use('ggplot')
ax = sns.barplot(x="date", y="Total1", data=df)
ax.set_xticklabels(ax.get_xticklabels(), rotation=45)

# add lineplot
sns.lineplot(x='date', y='Total2', data=df, marker='o')
plt.show()

以date作为日期时间索引

df['date'] = pd.to_datetime(df['date'])
df.set_index('date', inplace=True)


plt.style.use('ggplot')
ax = sns.barplot(x=df.index, y="Total1", data=df)
ax.set_xticklabels(ax.get_xticklabels(), rotation=45)
ax.xaxis.set_major_formatter(plt.FixedFormatter(df.index.to_series().dt.strftime("%Y-%m-%d")))

# use the ax labels as the x axis for the lineplot
locs, labels = plt.xticks()
label_t = [x.get_text() for x in labels]

sns.lineplot(x=label_t, y='Total2', data=df, marker='o')

plt.ylabel('Totals')
plt.show()
