带组的 Seaborn 中的堆叠条 Plot

Question

I would like to create a stacked bar chart showing for each Day_Since_Acquisition the number of Total_Customers for each Aquisition_Channel .

I am having issues creating a stacked bar plot out of this df that show on the X-axis on the values for Day_Since_Acquisition and nothing in between.

DF

Aquisition_Channel   Day_Since_Acquisition  Total_Customers
Digital              7                       10
Digital              14                      12
Digital              21                      16
Digital              28                      20
Organic              7                       32
Organic              14                      40
Organic              21                      41
Organic              28                      45
Offline              7                       23
Offline              14                      30
Offline              21                      46
Offline              28                      55

This is my current code:

fig = px.bar(df, x="Day_Since_Acquisition", y="Total_Customers",
             color="Day_Since_Acquisition", barmode = 'stack')
 
fig.show()

Answer 1

df2 = df.groupby(["Day_Since_Acquisition","Aquisition_Channel"]).sum().unstack("Aquisition_Channel").fillna(0)
df2["Total_Customers"].plot.bar(stacked=True)

The output chart is:
