Dot Plot Conditional Formatting Question

[Pdothard]

I'm fairly new to SAS (Enterprise Guide 6.1).  I'm using a dot plot within PROC SGPLOT to display observed to expected ratios with confidence limits based on the mean.  I have everything functioning the way I need it so far, but now I want to throw in some color coding based on the value of the limits.  Basically I want the limit and dot to change color if the upper limit is less than 1.0 or change to a different color if the lower limit is greater than 1.0.  Here is what I have so far:

PROC SGPLOT DATA=WORK.SORTTempTableSorted;

refline 1.0/ lineattrs=(color=blue thickness=1.5pt) axis=x;

By Site;

  dot AttendingNPI / response=DirectCostOERatio stat=mean

  limitstat=clm limitattrs=(color=bib) categoryorder=respasc;

RUN;QUIT
