Specify Y axis value in proc sgplot

[mcmaxwell]

Hi everyone, 

Is there a simple way to specify the maximum value to show on the Y axis in proc sgplot? I'm using the code below to make a simple bar graph and it returns a graph where the Y axis goes up to 15, but I would like it to go up to 20. 

ods graphics on / width=3.5in height=4.5in;  
proc sgplot data=new;        
	vbar cPLTL / response=percent group =cPLTL groupdisplay=cluster barwidth=.5;
	styleattrs datacolors=(CXFF8000 CX0000FF); 
	yaxis label="Percent of unsuccessful students";   
	xaxis display=(nolabel); 
	run;

yaxis label="Percent of unsuccessful students" values=(0 to 0.2 by 0.05);

yaxis label="Percent of unsuccessful students" max=20 ;
