AmiGO Manual: Bar Chart
From GO Public
Generating a Bar Chart
If a GO term is fully expanded (i.e. all its children GO terms are displayed), a bar chart icon will appear at the end of the line. Clicking on this icon will generate a bar chart showing the distribution of genes and gene products associated with that GO term and its children.
Understanding Bar Charts
The bar chart shows the distribution of all gene products associated for that GO term and its child GO terms. The bar chart is drawn on the top half of the page with the total number of gene products annotated to each GO each listed in a table below. The GO term name is a hyperlink that directs you to the term details page for that GO term.
Please note that the total number of genes and the percentages listed may not equal 100% because a gene product may be annotated to multiple children GO terms.
