Dear Maggie,
For what you are asking, you need to perform a regression. Go to the
Covariation menu, choose regression, then choose the Procrustes
coordinates (for data without object symmetry) or symmetrical component
(for data with object symmetry) for the dependant variable, and the
centroid size as the independent variable.
Perhaps the MorphoJ users guide can also be of help to you
(http://www.flywings.org.uk/MorphoJ_guide/frameset.htm?index.htm)
Best wishes,
Emma

Hi everybody, my name is Maggie and I am working with MorphoJ and
morphometrics to study shape variation in avian mandibles. We are
making
PC plots of our data and need to make a plot with Centroid Size on the
x-axis and Shape Score on the y-axis. Currently the graph has the first
principal component on the x-axis and the second principal component on
the y-axis. We aren't sure where to go in the program in order to
change
this and could use some help. If you could point us in the right
direction, we would be very thankful!
Sincerely,
