Shade a portion of a VBARBASIC using BLOCK statement.

data_null__ — Mon, 29 Jul 2024 16:06:24 GMT

In my VBAR chart I want to shade AGE=16 with a gray background. I have that working (AGE2=16) but I'm not able to figure out how to get the other block, (AGE2=. everything else) to have white background. I don't understand how to use ATTR parameters to get what I need.

data class;
   set sashelp.class;
   if age eq 16 then age2=age;
   else age2=.;
   run;
proc sort;
   by age sex;
   run;
proc print;
   run;
ods output sgplot=sglot;
proc sgplot data=class;
  styleattrs DATACOLORS=(Black Gray);
  vbarbasic age / nooutline
      group = sex
      groupdisplay=cluster
      response=Weight
      stat=mean
      ;
  block x=age block=age2 / novalues transparency=.9; 
  run;

In the figure I have AGE=16 shaded as I would like. I need to understand how get BLOCK AGE2=. not shaded or shaded with color=white.

Something like this should work for you:

proc sgplot data=class;
  styleattrs DATACOLORS=(Black Gray);
  vbarbasic age / nooutline
      group = sex
      groupdisplay=cluster
      response=Weight
      stat=mean
      ;
  block x=age block=age2 / novalues fillattrs=(color=white) 
      altfillattrs=(color=cxAAAAAA) transparency=0.9 filltype=alternate;
run;

Thanks @DanH_sas I will try this. I found another way using X=AGE2 BLOCK=AGE2

  block x=age2 block=age2 / 
      FILLATTRS=(color='GRAY')
   novalues transparency=.8;

I am not sure what you want for output. Can you point to an example somewhat like what you want?

I suspect part of the issues may be the MISSING values for age2.

See if this with light green/ red backgrounds looks somewhat like you expect. If the "green" should be white then change it.

I'm not really sure what color you want for the age 16, but I would specify that instead where I have red.

You might also want the BLOCK before the VBARBASIC to avoid shading the bar colors.

data class;
   set sashelp.class;
   if age eq 16 then age2='block2';
   else age2='block1';
   run;
proc sort;
   by age sex;
   run;
proc print;
   run;
ods output sgplot=sglot;
proc sgplot data=class;
  styleattrs DATACOLORS=(Black Gray);
  block x=age block=age2 / filltype=alternate fillattrs=(color=green) altfillattrs=(color=red) novalues transparency=.9; 

  vbarbasic age / nooutline
      group = sex
      groupdisplay=cluster
      response=Weight
      stat=mean
      ;  

run;

Actually, your way is better, as "age2" contains only the one bar you want to highlight. That way, you don't have to deal with any interactions with the other bars.
