This tool produces plots of stratified HUMAnN features and includes many options for sorting and scaling data

Here is an example of a HUMAnN barplot for a pathway (denitrification) that was preferentially enriched in Human Microbiome Project oral samples relative to other body sites.
This figure uses many options from humann_barplot, including regrouping by genus, pseudolog scaling, and sorting samples by similarity and metadata:
