No combined axes defined

[JoeRibeiro]

I am not calculating these combined axes.
For a simplified tool, I think this is okay. It should not affect performance of the model as the variables are all still in there - no information is lost. But it might make it harder for people who are used to seeing their data as cytograms of e.g. Red vs Orange/Yellow

Are the "combined axes" the same as the "ratios"? For example, FLR total/FWS total.

If so, I believe the ratios would only be worth using if we wanted to remove most of our features and work with fewer than ten predictor variables, or if we only wanted features that could be directly interpreted as ecological/functionnal traits. If this is not the goal, then they are not really useful and can be confusing when plotting (the original features should then be kept available for visualisation).
