ENFA scatter plot problem & habitat suitability map question

Hello,

I have a problem with my ENFA scatter plot. Data are from three 
different sites far from one another along the Mediterranean Sea.
You can find it in the atteched file.
The first scatter is made with the line command :

scatter(enfa_TOT,pts = FALSE, nc = TRUE, percent = 100)


After many tests I realized that the habitat used is not visible because 
it coincides with the x-axis. Do you have an idea about that?

I did the same scatter with the line command:

scatter(enfa_TOT,pts = T, nc = TRUE, percent = 100)....the result is 
below... Any idea about it?




Another question is about the habitat prediction map that I would like 
to do after the ENFA analysis. What method do you saggest to use to do that?


Thank you very much for your help.

Michela
