python – How to join two Dataframes and plot data as one line in graph using ‘date’ as index?(Plotly Express)

I’m trying to plot a line graph of two datasets that each contain the values ‘date’,’conversions’, and ‘cpi’ as one line. The graph displays a daily count of the values, so I’m having problems dealing with properly graphing the values of each data seat on the same day: enter image description here

The Dataframe used in this graph:

My code is:

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)

How can I fix the issue where two of the same dates are graphed?
