Graph titles are printed one by one-CodePudding

Graph titles are printed one by one. How can I solve this problem??

This is my code.

plt.figure(figsize=(25,10))
plt.subplots_adjust(left=0.125, bottom=0.1,  right=0.9, top=0.9, wspace=0.2, hspace=0.4)
n = 1

for idx, i in enumerate(top_10_df_event_copy['Code'].unique()):
    top_10_df_event_copy_list[i] = pd.Series(winsorize(top_10_df_event_copy_list[i].values, limits=[0, 0.1]))
    stl = seasonal_decompose(top_10_df_event_copy_list[i].values, freq=3)
    plt.title(f"{i}", fontsize=15)
    ax = plt.subplot(4,3,n)
    
    ax.plot(stl.seasonal   stl.trend)
    ax.plot(stl.observed, color='red', alpha=0.5)
    n  = 1
    print(i)
    

plt.show()

i = [90001302, 90001341, 90001441, 90001443, 90001521, 90001541, 90001542, 90001582, 90001602, 90001622]

Finally print(i)

90001302 90001341 90001441 90001443 90001521 90001541 90001542 90001582 90001602 90001622

but graph is printed like this picture.

There are 10 titles in 10 graphs, but in reality only 9 titles are output in 10 graphs.

plz help..
