Thank you all for your help; I have used both Rick's and Sanjay's code and have got what I need. This plot didn't have a reference line at 0 which was a shame so added the following 'refline' code proc sgplot; scatter y = rstudent x = var1; refline 0 / axis = y; run; Sorry for the delay in responding.

Hi Sanjay Please find below the code and the plot I require that I produced from SAS 9.4. The GFR dataset is attached. The plots that I am having problems with are bolded. I successfully get the standard diagnostic plots and residuals by x variables but receive the following error message from SAS Studio V 3.1 ERROR: Appendage SASXGANO not found, unable to produce graphics. I have seen discussions regarding this error message that say you should use the PLOTS = option which I have tried but there does not appear to be an option for rstudent by x variables just rstudentbypredicted or leverage.
