Data - Interaction Plot
main topic      

Set up your worksheet with one column for the response variable and one column for each factor, so that each row in the response and factor columns represents one observation. Your data is not required to be balanced.

The factor columns may be numeric, text, or date/time and may contain any values. If you wish to change the order in which text levels are processed, you can define your own order. See Ordering Text Categories. You may have from 2 through 9 factors.

Missing data are automatically omitted from calculations.
