Stacked Bar Plot

Microbiome community composition visualization. Relative abundance stacked bars with automatic normalization, top-10 taxa ranking and low-abundance groups merged as "Other".

Visualization Parameters

Upload an abundance table and generate the stacked bar plot

Upload Data File

Long format (Sample, Taxon, Abundance) or wide format (Taxon x samples)

Required Files

data.tsv — Abundance table: long or wide layout (auto-detected)

Format

Long format: Sample | Taxon | Abundance (3 columns)
Wide format: Taxon | Sample1 | Sample2 | ... (taxa as rows)
Abundance: raw counts or relative values (auto-normalized to %)
Top 10 taxa by mean abundance shown; others merged as "Other"
Layout is auto-detected from column types

Abundance Data (Long Format)

Active_1	Firmicutes	42.3
Active_1	Bacteroidetes	28.1
Torpor_1	Firmicutes	25.4

Documentation

Input format: an abundance table in either long format (Sample, Taxon, Abundance) or wide format (taxa as rows, samples as columns). The layout is auto-detected.

Processing: abundances are normalized to relative abundance (%) per sample; taxa are ranked by mean abundance and only the top 10 are shown individually — the rest are merged as "Other".

Typical use: phylum/genus-level microbiome composition (Microbiome workflow, 16S/ITS/metagenomic data), or any compositional comparison across samples.
