Understanding the PCA Plot from JMP

Hi All,

I am little confused understanding the PCA plot generated from JMP. In the plot below, products in the top-right quadrant are correlated positively, i.e. if one of them increases, all other increase ('am I right ?). What about the products in the lower-right quadrant and the upper left quadrant.

Thanks for your help

Cheers

I think this is loadings plot graph which indicates correlation between the variables and the components. The closer the value is to 1 the greater the effect of the component on the variable.
