Increase SGPLOT Margins

[acuffza]

I'm creating box plots of a specific size, but I'd like to increase the graph area--specifically, I want to make it taller since the small font size of the title leaves some white space. Does anyone know how to do this? I'm using SAS 9.4 on Enterprise Guide. Here's an example of my code and the graph it produces:

ods rtf file="Path/Cars Box Plots.rtf";
ods graphics / width=1.5in height=1.1in border=off;
proc sgplot data=sashelp.cars;
vbox horsepower / category=drivetrain fillattrs=(color=darkgray) whiskerattrs=(color=black) medianattrs=(color=black) meanattrs=(color=black);
title height=8pt "Horsepower by DriveTrain" ;
xaxis discreteorder=data display=(nolabel) valueattrs=(size=7pt);
yaxis labelattrs=(size=7pt) valueattrs=(size=7pt);
label horsepower="Horsepower";
run;
title "";

ods rtf close;
