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。该图显示了值的每日计数，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：

在此处输入图像描述

样本数据：

          date  conversions           cpi

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)： 在此处输入图像描述

  • 主要问题是两个数据帧的需要.groupby 'date'和.sum()值。
import pandas as pd
import plotly.express as px

# sample data
data1 = {'date': ['2020-11-02', '2020-11-03', '2020-11-04', '2020-11-05', '2020-11-06', '2020-11-07', '2020-11-08', '2020-11-09', '2020-11-10', '2020-11-11', '2020-11-12', '2020-11-13', '2020-11-14', '2020-11-15', '2020-11-16'], 'conversions': [0, 0, 0, 0, 3, 0, 0, 0, 0, 2, 0, 2, 0, 1, 2], 'cpi': [0.0, 0.0, 0.0, 0.0, 0.6333, 0.0, 0.0, 0.0, 0.0, 1.695, 0.0, 2.17, 0.0, 2.59, 2.67]}
data2 = {'date': ['2020-11-02', '2020-11-03', '2020-11-04', '2020-11-05', '2020-11-06', '2020-11-07', '2020-11-08', '2020-11-09', '2020-11-10', '2020-11-11', '2020-11-12', '2020-11-13', '2020-11-14', '2020-11-15', '2020-11-16'], 'conversions': [5.0, 6.0, 8.0, 8.0, 11.0, 14.0, 30.0, 27.0, 32.0, 4.0, 17.0, 20.0, 24.0, 38.0, 22.0], 'cpi': [2039435.0, 2788452.0, 1720630.0, 2038703.0, 1775534.0, 1810215.0, 1617934.0, 1784663.0, 1368291.0, 5293594.0, 1524248.0, 2437085.0, 2272977.0, 1848160.0, 2415721.0]}

# create dataframes
df1 = pd.DataFrame(data1)
df2 = pd.DataFrame(data2)

# concat the dataframes
df = pd.concat([df1, df2]).reset_index(drop=True)

# set the date column as a datetime
df.date = pd.to_datetime(df.date)

# groupby date, aggregate sum on all columns and reset 
dfg = df.groupby('date').sum().reset_index()

# plot
fig = px.line(dfg, x=dfg['date'], y=dfg['conversions'], title='Installs per Day')
fig.show()

display(dfg)
