Is it possible to control marker size by timepoints ? I want the marker size little bit bigger for the last visit for each patient.
I am using PROC SGPLOT and doing line plot of lab values by visit.
GTL SCATTERPLOT has a SIZERESPONSE=num-variable option, so you can size each marker by the value in this column. See GTL documentation. Alternatively, you can use the SGPLOT BUBBLE plot to draw circular markers with size variable.
proc sgplot data=sashelp.class;
bubble x=height y=weight size=age;
