What inspired this wish list request?
An interaction plot is a great tool for beginners, which also offers an overview of confounding. Interaction-plot is implemented in the tool "fit model", but newcomers will mainly use the graph menu.
For a simple case of two X's, it can be easily created in the graph builder but it will be harder for more than 2 X's.
What is the improvement you would like to see?
Please, implement "interaction plot" according to the tool "fit model" within the graph menu. An option could be, that x and y could be selected and the complete 2-way interaction matrix will be created.
Why is this idea important?
It is necessary to understand interactions. There is no need to create a model to understand interactions. Until now interaction plots are hidden in "fit model" and it should be more visible especially for beginners. A specific item "interaction plot" in the graph menu would be very helpful.
