如何使用 plotly-express 合并两个 Dataframes 并将数据绘制成一条线
How to combine two Dataframes and plot data as one line using plotly-express
我正在尝试绘制两个数据集的折线图，每个数据集都包含值 'date'、'conversions' 和 'cpi' 作为一条线。该图表显示了每天的值计数，因此我在处理同一天正确绘制每个数据集的值时遇到了问题：
示例数据：

14 2020-11-16 22.0 2.415721e+06
我的代码是：
asa_installs_time = get_installs_time(start_date, end_date)
ga_installs_time = get_GAinstalls_time(start_date, end_date)
asa_installsTime_df = pd.DataFrame.from_dict(asa_installs_time[1])
ga_installsTime_df = pd.DataFrame.from_dict(ga_installs_time)
all_installsTime_df = pd.concat([ga_installsTime_df, asa_installsTime_df])
installs_time_series_chart = px.line( all_installsTime_df, x= all_installsTime_df['date'], all_installsTime_df['conversions'], title='Installs per Day')
return [all_installsTime_df]
如何解决绘制两个相同日期的问题？
编辑
使用all_installsTime_df = all_installsTime_df.sort_values('date').reset_index(drop=True)：
- 主要问题是需要
.groupby 'date' 和 .sum() 来自两个数据帧的值。
