HREFLABELS and HREFLABPOS options are available is SAS/QC & SAS/STAT, it would be really useful to have these available is SAS/GRAPH too in order to label VREF & HREF lines easily. Currently the only way to do this is with PROC ANNOTATE which is clumsy and difficult especially if you keep redrawing the graph and moving the reference line.
These 2 options are already written and it would make life so much easier in SAS/GRAPH if they were incorporated.
