Adds/overwrites the y of the projected data. Usefully for 1D projections and appending information related to, but independent from the projection; model predictions or residuals for instance. Wants to be called early so that the following proto calls adopt the changes.
append_fixed_y(fixed_y)Vector of length of the data, values to fix vertical height. Typically related to but not an explanatory variable, for instance, predicted Y, or residuals.
