Venn Diagram

A Venn diagram shows which members are unique to each set and which members are shared between sets.

Prepare a directly mappable table

Venn diagrams are suitable for gene lists, sample IDs, compounds, pathways, or any text identifiers that need set-overlap comparison.

Use 2-4 columns. SmartPlot treats every non-empty unique value in each selected column as a member of that set.

Use Venn diagrams to compare overlap among 2-4 sets. Each selected column is treated as one set, and non-empty unique text values become set members.

Step 1

Confirm the data range, then choose a new figure or add the plot to an existing figure.

Step 2

Map Set A, Set B, Set C in order, making sure each selected column has the intended table role.

Step 3

Set Set labels, Duplicate members for the table structure and confirm that the choices match the intended reading.

Step 4

Check Blank cells are ignored, Case rules are consistent, review the mapped-column count, then choose Create figure.

Remove accidental spaces or inconsistent capitalization before plotting.
Use Venn diagrams for 2-4 sets; for more sets, an UpSet-style view is usually easier to read.
Counts come from exact member matching, so duplicate values inside one set are counted once.
Area size is a layout aid unless an explicit proportional layout is selected.
Export the intersection member table when the exact genes or samples are needed.
