I have run a proc glm model (Outcome = continuous with two continous predictors). With the Ods Graphics and Plots active it provided the below contour plot. I love components of this plot for explaining the project.
However, my final model has 3 continuous predictors, so SAS does not generate the plot. I would like to reproduce the plot without the color contouring and I would like the dots to be color coded based on the quartiles of the third predictor. Which this seems achievable, but i have no idea how to put on the diagonal lines that represent the dependent variable into a graph.
So dataset would contain
Y: continous variable
X1: continuous variable
X2: continuous variable
X3: continuous variable, categorized into quartile and used to shade observations on the plot.

ods graphics on ; proc glm data=dka_please PLOTS=all; model HOURS_PH_NORM = total_fluid INTITIAL_PH; run; ods graphics off;
Code is above for 2 IV model. In the final graph I would like to use labels to get rid of "_" and add units to variable names.
Side note, your Sim book was great Rick.
