OUTLINE Colors in SGPLOT HISTOGRAM

[Junyong]

I am drawing HISTOGRAMs using SGPLOT. I am seeing the HISTOGRAM and STYLEATTRS parts in the SAS manual, but couldn't find how to change the OUTLINE colors. This is the minimum sample code.

data have;
call streaminit(1);
do i=1 to 5000;
x=rand("t",3);
output;
end;
run;
ods listing gpath="!userprofile\desktop\";
ods graphics/reset;
ods results=off;
proc sgplot noautolegend;

HISTOGRAM X/NOFILL;

density x/type=normal(mu=0 sigma=1) lineattrs=(color=red);
xaxis display=(nolabel) values=(-6 to 6 by 1);
yaxis display=(nolabel);
run;
ods results=on;

The NOFILL option makes the bars white and their outlines black.

I tried to change this black using FILLENDCOLOR and STYLEATTRS DATACONTRASTCOLORS but didn't work. What should I do if I want to make the outline colors of the histogram bars blue?

From the documentation for the STYLEATTRS statement:

At least one plot statement must specify the GROUP= option in order for the data attributes to take effect. This requirement applies to the DATACOLORS=, DATACONTRASTCOLORS=, DATALINEPATTERNS=, and DATASYMBOLS= options.

Since none of the shown code shows a Group= option then styleattrs statement is not having any affect.

So one way is to add a group variable that styleattrs can affect:

data have;
call streaminit(1);
do i=1 to 5000;
x=rand("t",3);
xgroup=1;
output;
end;
run;
proc sgplot data=have noautolegend;
styleattrs datacontrastcolors=(orange blue);
HISTOGRAM X/NOFILL group=xgroup;

density x/type=normal(mu=0 sigma=1) lineattrs=(color=red);
xaxis display=(nolabel) values=(-6 to 6 by 1);
yaxis display=(nolabel);
run;

or go to GTL.
