how to cut y-axis title split to two rows in proc sgpanel

[Cruise]

Hi Folks:

Any idea how to split y-axis title in the plot shown below into two rows? so title would appear a whole? Thank you!

ods graphics/width=11in height=3in;
proc sgpanel data=mydata;
panelby SORT/ novarname columns=4 rows=1;
styleattrs DATACONTRASTCOLORS=(BLUE green red);
series  x=FU y=HazardRatio/lineattrs=(pattern=solid thickness=2) GROUP=S;
REFLINE 1 / LABEL = ('HR=1')  lineattrs=(color=black pattern=solid thickness=1) labelpos=min; 
colaxis label='Weeks' min=1 max=100 grid values=(0 to 52 by 1);
rowaxis label='Hazard Ratio Between Midpoint Imputation and Gold-Standard' 
fitpolicy=thin grid  values=(1 to 1.5 by 0.1);
keylegend/  title="Cancer Stage" position=TOP;
run;

The split options are for tick marks I think. I couldn't find a way to split that title. Sorry.

Thank for letting me know. Knowing this, I shortened my title to fit. The shorter title actually worked out better.

Maybe you could post it at ODS Graphic forum . There are more smart Graphic guys in it .

I'm satisfied with the shorter title given moving forward is being more important. Thanks Ksharp.
