Hi, I am interested in creating an individual trend plot for CD4 count over time per person with a regression line.The problem is that proc gplot ignores the symbol2 statement in my syntax and so the plot only has the individual trend lines and no regression line. The code is below: goptions reset=all; proc gplot data=dataset; plot cd4count*time=id/nolegend haxis=-1 to 300 by 10 vaxis=0 to 2000 by 100; plot2 cd4count*time; symbol1 v=none repeat=369 i=join color=red width=1; symbol2 v=none i=r color=blue width=3; label time='Months since seroconversion'; run; I'll appreciate any help in fixing this issue. Thanks ... View more
