Hello,   My question is relative to the information that is displayed when we are hovering the mouse on a graph made with PROC GPLOT like the one that follows:   PROC GPLOT DATA=dateset;       PLOT Y * X = Z; RUN;   When we are hovering the graph with the mouse there is a popup that comes out and display the information for the 3 X, Y and Z variables. How could we (if possible) display the value of a 4th variable?   I hope my question is clear enough.   Thanks in advance.       ... View more

Hi all,   I am trying to model a continous variable across the time with several timepoints (0,3,6,9 and 12 months) and 2 predictors.   One is continuous (5 and 10) and the other is categorical (A, B and C) and for each of the combinaison I have 30 replicates.   The relation between Y and the time is not expeted to be linear. My main concern is to study the behavior of Y along the time and see if the 2 predictors included in the experiment have an influence.   Which statistical methodology/SAS procedure would you recommend?   Here is what I've used so far:     ODS GRAPHICS ON; PROC GLM DATA=STUDY PLOTS=ALL; CLASS Component; MODEL Y = Timepoint Timepoint*Timepoint Component Essai Essai*Timepoint Timepoint*Component / SOLUTION; OUTPUT OUT=STUDY_results PREDICTED=pred RESIDUAL=res COOKD=Dcook RSTUDENT=rstud; RUN;     Thanks in advance.   Cédric. ...

Hello everyone,   I'm a newbiein the use of annotate function in PROC GPLOT.   I try to generate graphs where the annotate help me to visualize changes (symbolised by vertical bars)   Here is the table I use to do to perform the annotate:       Then, I draw two 2 graphs.   the first one plotting coefficient by date_m and colored by Identifiant with the annotation which gives this result (works):   proc gplot data=MaCouleur;      plot Coefficient * Date_M = Identifiant / annotate= anno; run;   The 2nd graph is pretty much the same as we color by variable Couleur and not Identifiant   proc gplot data=MaCouleur;      plot Coefficient * Date_M = Couleurs / annotate= anno; run;   As you can see, the vertical bars are no more visible.   Someone would have any idea from where this comes from?   Here is the message I get from SAS log:   NOTE: ERROR DETECTED IN ANNOTATE= DATASET WORK.ANNO. NOTE: PROBLEM IN OBSERVATION     1 -       A CALCULATED COORDINATE LIES OUTSIDE THE VISIBLE AREA             I hope my problem statement is clear enough to you. I suppose it is related to memory but I have no clue about how to be sure of it.   thanks in advance. ... View more
