I am using the following code (pay attention to symbol3 in particular):
goptions reset=all;
Proc Gplot data=set5;
plot ucl*N=alpha / vaxis=axis1 haxis=axis2 legend=legend1 vref=.03 cvref=ltgray lvref=2 noframe;
symbol1 c=yellow i=join h=.5;
symbol2 c=lime i=join h=.5;
symbol3 v=dot cv=black pointlabel=("#threshold" c=black position=top);
axis1 order=(0 to .5 by .1) label=(a=90 c=black "Upper Confidence Limit (%)")
value=(h=1.5 '0%' '10%' '20%' '30%' '40%' '50%') minor=(number=1) color=black;
axis2 order=(10 to 120 by 10) label=(c=black "Patients Enrolled")
value=(h=1.5) minor=none color=black;
legend1 position=(inside top right) value=(c=black h=1.5 "95% CL (Alert)" "80% CL (Watch)" "Threshold")
label=none down=3 across=1;
Run; Quit;
Threshold is a fourth variable (UCL*N), the values of which I want to use as labels at a few given values of N and UCL, along the lines represented by symbol1 and symbol2. The dots are placed appropriately, but the actual pointlabels are missing. This is the note from the log:
NOTE: At least one pointlabel has overwritten a boundary. This resulted in the affected pointlabel(s) being repositioned.
I do not understand what it means?
