Taxonomy composition analysis Statistics and visualization of specific levels

[jcogier]

Dear all,

When I use the Taxonomy composition analysis (class taxa, at the species level), I have 90% of the histogramm which is reprensented by the category "others", and the Top 30 major species did not appear in the figure. I wonder how to suppress the catergory "other" in order to see the 30 most abundant taxonomy species.

Thanks
