Rank Plot

This plot shows the inferred ranking of the species (or other taxa) along an

environmental variable presented in the biplot. It will enable you to identify species

that are particularly positively or negatively correlated with the chosen environmental

variable. It will also allow you to present the species in order of preference for the

chosen environmental variable. The position of each species is projected onto the line

formed by the environmental vector. Please note that while the lines are projected at

right angles, they will not appear so until you adjust the shape of the graph by

changing the window or the axes. To adjust the graph axes click on the Edit graph

button above the plot and select Axis.

The environment is selected using the Plot Environment drop down menu below the

graph and labels can be added or removed by clicking on the Show labels tick box.
