I would like to visualisize bone morphological variation along PC scores of multiple linear measurements. Those measurements are not all interconnected -as could be ideal for a truss- and they were collected using traditional calliper. Based on the correlation matrix I can always see that PC1 highly correlates with the overall bone length but I would like to see this variation like we could do in geometric morphometrics with TPS. Is there anyone having experience visualising objects from measurements? The idea will be to go from linear measurement back to raw coordinates as long as we can find spatial correspondence (I can trace back the "approximately" exact position of what I measured on the bone). I double checked the literature and I find only a visualisation example -I guess manual drawing- in DeGusta & Vrba (2003) Journal of Archaeological Science 30: 1009-1022, Fig.4 page 1018. Any suggestion on software or statistical methods would be really appreciated.
Dear Carlo, I'm not sure if this is of any help in your particular case but you might find interesting the following chapter: Carpenter KE, HJ Sommer III, LF Marcus. 1996.
