I want to plot 2 100% stacked bar charts for Total Products Sold and Total Profit each, where the x-axis is Week Days and the labels are the different Categories.

My code for Total Products Sold is

df5 = df5.set_index(['Week_Days', 'Category'])
df5 = df5.div(df5.sum(1), axis=0)
ax = df5[['Total_Products_Sold']].plot(kind='bar', stacked=True, width = 0.3, figsize=(20, 10), colormap="RdBu")
patches, labels = ax.get_legend_handles_labels()
ax.legend(bbox_to_anchor=(1.1, 1.0))
ax.set_xlabel('Week Days')
ax.set_ylabel('Products Sold')

The graph I got returned looks nothing I need. It is not 100 stacked and the legend is Total Products Sold and not the different categories in Category.

Can someone please help? Thanks.

Lobbie

The easiest way is to make a pivot table with the values you care about. Try something like this:

tps = df5.pivot_table(values=['Total_Products_Sold'], 
                      index='Week_Days',
                      columns='Category',
                      aggfunc='sum')

tps = tps.div(tps.sum(1), axis=0)
tps.plot(kind='bar', stacked=True)

For me this produces the following:

You can do the same thing for Total_Profit separately.
