Plot stacked bar chart

Question

I have a pandas dataframe representing a table with 2 columns and 4 rows

Name | Value
 n1  | 10.3
 n2  | 5
 n3  | 15
 n4  | 8

I need to draw stacked bar (matplotlib) of values and the names should be shown in legend I tried this (with no success):

df.count().unstack('Total_Sales')
df.plot(kind='bar', stacked=True)

How can I do it? I saw this question Pandas - Plotting a stacked Bar Chart. Not sure how to use it in my case

Answer 1

If you want to use the names as categories you need to have them in the columns. So first set the index to 'Name' and then transpose.

df.set_index('Name').T.plot(kind='bar', stacked=True)
