Given the independent variable (x) and two regulating variables (M1 and M2), if we want to plot a three-way interaction diagram, which interaction items need to be calculated? After obtaining the estimated parameters of these interaction items, which software or plug-in can be used to draw the three-way interaction diagram?
Thanks & Regards
The ggplot function being part of the R ggplot2 package might be the easiest way to draw a 3-way interaction.
Look at the Appendix (understanding ggplot2) of the online R Graphics Cookbook:

the basics are : aes(x = X-variable, y = Y-variable, group = 'regulating variable')
@Jinnan This tuitorial video talks about three-way interaction affect. Please go to the end of the video to learn how to plot three way interaction effect.

Hello Jinnan Wu. You included Mplus as a topic. Does that mean you are asking how to plot the 3-way interaction using Mplus?
Also, you have not said whether variables X, M1 and M2 are all quantitative, categorical, or some of each. Please clarify.
In my lab we use the Jeremy-Dawson excel to plot the three-way interactions. It is an excel template that you only have to introduce the required data.
