You asked why you could not get two discriminant functions and that question
was answered. The number of discriminant functions is one less than the
number of groups (assuming you have more variables than groups). Now you are
asking a different question. How to plot the discriminant boundary between
the groups in a plot of the original variables. Time to provide "provide
commented, minimal, self-contained, reproducible code" [including data] as
called for at the bottom of your message.
