I want to create a version of the forest plot here: http://support.sas.com/kb/42/867.html
Unfortunately, the scale isn't useful for the values I want to include (Hedge's g instead of odds ratio), which range from ~-2 to +8. If I include a negative number in the datalines, the whole plot becomes unreadable.
Is it possible to rejig the code to accommodate the scale? I'm not overly familiar with SAS, so my coding skills are fairly limited.
Part of the code that I've tried editing to no avail:
proc sgplot data=forest4 noautolegend;
scatter y=study2value x=oddsratio / markerattrs=graphdata2(symbol=diamondfilled size=10);
scatter y=studyvalue x=oddsratio / xerrorupper=ucl2 xerrorlower=lcl2 markerattrs=graphdata1(symbol=squarefilled size=0);
vector x=x2 y=studyvalue / xorigin=x1 yorigin=studyvalue lineattrs=graphdata1(thickness=8) noarrowheads;
scatter y=studyvalue x=or / markerchar=oddsratio x2axis;
scatter y=studyvalue x=lcl / markerchar=lowercl x2axis;
scatter y=studyvalue x=ucl / markerchar=uppercl x2axis;
scatter y=studyvalue x=wt / markerchar=weight x2axis;
refline 1 100 / axis=x;
refline 0.1 10 / axis=x lineattrs=(pattern=shortdash) transparency=0.5;
inset ' Favors Treatment' / position=bottomleft;
inset 'Favors Placebo' / position=bottom;
xaxis type=log offsetmin=0 offsetmax=0.35 min=0.01 max=100 minor display=(nolabel) ;
x2axis offsetmin=0.7 display=(noticks nolabel);
yaxis display=(noticks nolabel) offsetmin=0.1 offsetmax=0.05 values=(1 to &count by 1);
run;
Many thanks for any help
