I have three dataframes df_Male , df_female , Df_TransGender
sample dataframe df_Male
continent avg_count_country avg_age
Asia 55 5
Africa 65 10
Europe 75 8
df_Female
continent avg_count_country avg_age
Asia 50 7
Africa 60 12
Europe 70 0
df_Transgender
continent avg_count_country avg_age
Asia 30 6
Africa 40 11
America 80 10
Now our stacked bar grap should look like
X axis will contain three ticks Male , Female , Transgender
Y axis will be Total_count--100
And in the Bar avg_age will be stacked
Now I was trying like with pivot table
pivot_df = df.pivot(index='new_Columns', columns='avg_age ', values='Values')
getting confused how to plot this , can anyone please help on how to concatenate three dataframe in one , so that it create Male,Female and Transgener columns
This topic is handeled here: https://pandas.pydata.org/pandas-docs/stable/merging.html
(Please note, that the third continent in df_Transgender
is different to the other dataframes, 'America' instead of 'Europe'; I changed that for the following plot, hoping that this is correct.)
frames = [df_Male, df_Female, df_Transgender]
df = pd.concat(frames, keys=['Male', 'Female', 'Transgender'])
continent avg_count_country avg_age
Male 0 Asia 55 5
1 Africa 65 10
2 Europe 75 8
Female 0 Asia 50 7
1 Africa 60 12
2 Europe 70 0
Transgender 0 Asia 30 6
1 Africa 40 11
2 Europe 80 10
btm = [0, 0, 0]
for name, grp in df.groupby('continent', sort=False):
plt.bar(grp.index.levels[1], grp.avg_age.values, bottom=btm, tick_label=grp.index.levels[0], label=name)
btm = grp.avg_age.values
plt.legend(ncol = 3)
As you commented below that America
in the third dataset was no mistake, you can add rows accordingly to each dataframe like this bevor you go on like above:
df_Male.append({'avg_age': 0, 'continent': 'America'}, ignore_index=True)
df_Female.append({'avg_age': 0, 'continent': 'America'}, ignore_index=True)
df_Transgender.append({'avg_age': 0, 'continent': 'Europe'}, ignore_index=True)
