Hello every one, Iam having trouble interpreting a margins plot and the margins output as well whiile doing latent class analysis. All my variable are categorical in nature. Below is my margins out put and my margins plot

Predictive margins Number of obs = 1,254

1._predict : Predicted mean (any transactional sex), using class probabilities, predict(mu outcome(tsany))
2._predict : Predicted mean (Alcohol abuse problem), using class probabilities, predict(mu outcome(alcoprob))
3._predict : Predicted mean (any drug use), using class probabilities, predict(mu outcome(druguse))
4._predict : Predicted mean (Has woman been pregnant, man impregnated a woman), using class p, predict(mu outcome(anypreg))
5._predict : Predicted mean (any casual sex ), using class probabilities, predict(mu outcome(anycas))

Unfortunately am unable to show the graph since am unable to paste for whatever reason i dont know why it cant paste onto here. tnhough the graph connects the above given values to each other. My question is what do those jointed lines mean?

Thanks in advance.
