Hello everyone,

I have a question regarding the adequacy of using a linear visualisation plot for an interaction effect of a continuous criterion variable, a dummy predictor variable and a dummy moderator variable. Since the association between these variables is not linear (because of the dichotomous nature of the predictor and moderator), is there an alternative plot to visualise this? Apparently, many people use a linear graph for such purpose, at least this is what my research pointed towards. In some cases boxplots were used, but I find the interpretation of this graph less intuitive and understandable.
I calculated an OLS regression and used marginsplot to visualize my results, if this is important to know.

I would be very thankful for any advice or insight on this matter.

Kind regards,
Ava.

PS: I added an example of my plot so you know how it looks at the moment.
