[FIXED] Creating histograms for mulitple IDs in pandas dataframe

Issue

I have a dataset like:

    Count          ID      size 
0   25             0001    1     
1   4              0001    2    
2   9              0001    3    
3   13             0001    4     
4   19             0001    5    
...          
8   11             0003    10           
9   10             0003    12              
10  7              0003    14              
11  15             0003    16 

The objective is to plot a histogram for each unique ID, with the size on the x-axis as the boxes and the count on the y-axis is count. I've tried using the following code:

df = pd.DataFrame(data)

for d in df.groupby(df['ID']):
    plt.hist(d[1][['size','Count']])
    plt.show()

However, this does not give me the desired result as this is the way to plot a normal graph but not a histogram. Unfortunately, I have not been able to figure out how to tackle this problem.

Solution

I think you might want barplots, not histplots. You can use seaborn.catplot:

import seaborn as sns
sns.catplot(data=df, x='size', y='Count', col='ID', kind='bar')

output:
