AXIS statement for PROC BOXPLOT

Hi, I opened a ticket with SAS Tech Support one week ago and they have not been able to help me. I am trying to use an AXIS statement with PROC BOXPLOT and what I am specifying in the AXIS statement does not appear in the resulting output (in either the .lst file or the .rtf file). Here is the code that I am using.

symbol color = blue h = .8;
goptions ftext=swiss cback=white;
axis1 minor=none color=black label=(angle=90 rotate=0);
axis2 label=none /*order=(1 to 2 by 1)*/ major=(h=.8) value=(t=1 h=3 j=c "(N=&phase1)" t=2 h=3 j=c "(N=&phase2)");

title 'Box Plot for Infusion Duration by Phase';
proc boxplot data=phase;
plot INF_DURN * PHASE_ENRL/ cframe = vligb
cboxes = dagr
cboxfill = ywh
vaxis = axis1
haxis = axis2;
run;

The axis1 statement (for the vaxis) works just fine. However, the axis2 statement (for the haxis) has absolutely no effect. What I am trying to do is show the number of subjects in the two groups on the horizontal axis. I create macro variables for &phase1 and &phase2. When I run the program using the SYMBOLGEN option it shows that these two marcro variables do resolve. So that is not the problem.

Hi @cgsmaok56 and welcome to the SAS Support Communities!

With this AXIS statement

axis2 label=(h=2 "Group") order=(1 to 2)
      major=(h=.8) value=(t=1 h=2 "1" j=c h=2 "(N=&phase1)"
                          t=2 h=2 "2" j=c h=2 "(N=&phase2)");

and values of 123 and 456 for the two macro variables I obtain this x-axis:

(using Windows SAS 9.4M5 and a sample dataset PHASE containing values 1 and 2 for variable PHASE_ENRL and random INF_DURN values).

Alternatively, you could keep your label=none and use, e.g., "group 1" and "group 2" (rather than "1" and "2") as tick mark labels.

Thank you. The solution worked.
