traj command in Stata not supporting more than 2 variables?

[Thien-Kim Trinh]

Hi,
I have an issue with the traj command, where the third variable does not show up in the graph no matter what that variable is. When testing two and two variables, all the variables seem fine. Does anyone know if the traj command does not support more than 2 variables?

This is my code

traj, var1(AD_*) indep1(intervals_*) model1(logit) order1(1) var2(somaticdr_*) indep2(intervals_*) model2(logit) order2(1) var3(psychotropic_*) indep3(intervals_*) model3(logit) order3(1)
