1.19 Venn Diagram

Summary

The Venn Diagram app is used to show all overlaps among a collection of different group columns, and reveal the possible logic relationships.

Tutorial

Create a new worksheet. Import the sample file <Origin Porgram Folder>\Samples\Statistics\Fisher's Iris Data.dat by selelcting Data: Connect to File: Text/CSV menu.

Highlight Col(A)~Col(D) to click on the Venn Diagram app icon File:Venn Diagram icon.png to open the dilaog.

Export Detailed Overlap List	Check it to generate a detailed breakdown, (“VennData” worksheet) of which data points fall into each unique overlap region of the Venn diagram. See Results and Interpretation section for explanation of binary codes.
Use Classic Background	Classic circular Venn diagram with overlapping circles (standard colors), on a white or plain background. For 4-way or 5-way plot, a static(classic) background must be used. The tutorial shows you a 4-way diagram: https://docs.originlab.com/app/venn-diagram/ For 3-way plot, the Venn diagram can have classic background checked or unchecked. See the difference in the image below. File:3 way Classic Background Comparison.png
