I have a similar problem using SAS 9.4.   I have added "NOOUTLIERS" and "xaxis type = discrete". However, 2 points with y-values 2.4 and 2.44 are still overlapping. It seems the jitter function is not working   Could you please assist me in finding out why jitter function is not working?   Here the code : proc sgplot data=mydata noautolegend noborder;   scatter y=level x=Group/ jitter jitterwidth=1 group=group  markerattrs=(size=10);   vbox level/ category= Group group = group discreteoffset=0.2 boxwidth=0.3 nooutliers /*nofill*/ dataskin=gloss  nomean;   xaxis type = discrete display= (nolabel noticks) values=("Bill" "Aman" "Rude") valueattrs=(Color=Black Family=Arial Size=16);   yaxis display=(noline noticks) label= "Levels"  labelattrs= (Color = Black Family = Arial Size = 16) grid valueattrs=(Color=Black Family=Arial Size=16); run; quit;   Thank you! ...
