Plotting in horizontal with percentage on the bar-CodePudding

I have the following data frame say df =

FunderCode                  
HCPL1   1%  18% 50% 30% 1%
HCPL2   1%  16% 44% 37% 3%
HCPL3   1%  17% 40% 39% 3%
HCPL4   1%  20% 40% 34% 5%

I wanted to plot it like the following

I could get the following using

Piv_age_per.plot( kind = 'bar', stacked = True , legend = True)

I wanted a diagram with percentage on the bars, if there is inbuilt command to achieve that? g plot I could use the following code to generate
