This is my Proc Gplot code and using this code I am getting couple of warnings and green notes How to avoid them. And one simple question this is code I am using from other study not sure weather the resultant Graph is right or wrong , How do we validate the graph results ??

PROC GCHART DATA = final ; by visitnum ; format trtgrp trt. visitnum vst.; VBAR cp/ discrete SUMVAR = pctchange group=trtgrp gspace=2 space=3 width=3 nozero vref=0 LREF=2 patternid=group RAXIS = AXIS1 MAXIS = AXIS2 gaxis = axis3 ; run; quit;
