How can I draw a bar graph from three different data frames using matplotlib?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I want to draw a triple bar graph with three different dataframes using matplotLib



DF1



index | Number    
A | 110
B | 22
D | 52


DF2



index | Number
A | 100
B | 22
C | 52


DF3



index | Number    
A | 90
B | 12
C | 10


I am trying to use this piece of code but this is giving error as for this data needs to be from same dataframe



ax=DF1[["Number"]].DF2[["Number"]].DF3[["Number"]].plot(kind ='bar',log=True,title = "BarGraph",figsize=(15,10),legend=True,fontsize=10)
ax.set_xlabel("Index",fontsize=12)
ax.set_ylabel("Number",fontsize=12)
plt.show()

  • Why don’t you use Seaborn instead?

If you are willing to use seaborn, this code chunk works for you:



import pandas as pd
import seaborn as sns

DF1 = pd.DataFrame({'index': ['A', 'B', 'C'], 'Number': [110, 22, 52]})
DF2 = pd.DataFrame({'index': ['A', 'B', 'C'], 'Number': [100, 22, 52]})
DF3 = pd.DataFrame({'index': ['A', 'B', 'C'], 'Number': [90, 12, 10]})

DF = pd.concat([DF1, DF2, DF3])
DF['df_num'] = ['1','1','1','2','2','2','3','3','3']

sns.barplot(data = DF, x='index', y='Number', hue='df_num')


It should produce this plot:



seaborn plot
