Question

I am plotting a barplot using the seaborn.barplot method. The plotting is going through fine. When I am trying to add text on above the bars for better explanation using text method I am running into above mentioned issue.

Below is the code I have tried. With this code I am getting plot like this but i need plot like this

where values displayed at top of bar are the raised_amount_in_millions value

Here is my code

 groupedvalues=master_frame_backup1.groupby('funding_round_type')['raised_amount_in_millions'].mean().reset_index()

 #groupedvalues
 plt.figure(figsize=(30,8))
 pal = sns.color_palette("Greens_d", len(groupedvalues))
 rank = groupedvalues["raised_amount_in_millions"].argsort().argsort() 
 g=sns.barplot(x='funding_round_type',y='raised_amount_in_millions',data=groupedvalues, palette=np.array(pal[::-1])[rank])
 for index, row in groupedvalues.iterrows():
     g.text(row.funding_round_type, row.raised_amount_in_millions," "+str(row.raised_amount_in_millions), color='black', ha="center")

  plt.show()

But I am running into above mentioned error. Any help?

Here is the error stack
