Just now, I have send you an Email, and ask the question of how to plot
CCA structural correlations figure. Now I have gotten that figure (please
see the attachment), But I can’t see anything from this figure, I only know
blue triangle is represent environment factor, and red diamond is for
metabolic pathway. But I don’t know what does this specified red diamond
represent which pathway, and what is for this triangle?
