Proc SGPLOT values list

[Leo9]

I am creating a graph where I want to display only specific ticks. For some reason, the plot is not displaying all the values which I am providing. Below is the code. In the case, I am passing tickvalues as a macro parameter. The values for ticks which I am passing 

are : 3, 3.18, 3.48, 4, 6,8,10,12

How can I display all the ticks on y-axis ?

proc sgplot data = lbs ;
format lbstresn tcfmt. ;
series x = weeks y = lbstresn / group = subjid groupms=subjid markers markerattrs=(size =4);
yaxis label = &lbl values =(&ticks) display = all/* min = &valu5*/ ;
xaxis values= (0 to 24 by 1 ) label = "Weeks" display = all ;
refline &valu4/ label = "LOQ = &valu3 " labelattrs = (size = 6) labelloc=inside;
keylegend / valueattrs = (size=6) title = 'Subjects' ;
run;

What does your graph output look like?  Some tick values may be dropped due to collision.  Try using FITPOLICY=none to see all values.

Providing full code with data helps to see what is going on, and the version of SAS you are using.
