I am trying to get a bar plot for feature importance in the XGBoost classifier. It should have worked but it didn't. I tried too many times. Can you check the code below and tell me what is wrong with it?

feat_import=clf.feature_importances_
feat_names=X.columns
sorted_idx=clf.feature_importances_.argsort()[-20:]
plt.barh(feat_names[sorted_idx], clf.feature_importances_[sorted_idx])

It takes the features that the most important ones. However, it plots them unsorted.

When I use just numbers instead of column names I take the sorted bar graph.

plt.barh(range(20),feat_import[sorted_idx])

I couldn't figure out the problem here.

You could sort the dataframe by a column you want using `sort_df = df.sort_values(by=['columnName'], ascending=False)` – DataNoob Feb 23 '21 at 19:52
It is a good idea. Thanks. – tbuyar Feb 23 '21 at 20:13
