How to change color of segment label text inside bar

cuevasj — Thu, 07 Nov 2019 19:14:05 GMT

This is an example of what I have using sashelp:

data myattrs;
length value fillcolor $12;
show='AttrMap';
id="jrc_ID";
value=11; fillcolor='red'; output;
value=12; fillcolor='yellow'; output;
value=13; fillcolor='green'; output;
value=14; fillcolor='blue'; output;
value=15; fillcolor='black'; output;
value=16; fillcolor='cyan'; output;
run;

proc summary data=sashelp.class nway;
class age;
var weight;
output out=class mean=;
run;

proc sgplot data=class dattrmap=myattrs;
vbarparm category=age response=weight / group=age seglabel dataskin=matte attrid=jrc_ID datalabel;
run;

What I would like to do is set the color of the font inside the each bar to a different color, for example blue bar = yellow font, green bar = white font, cyan bar = black font, etc.

I tried seglabelattrs but it will only take one color for the font.

Any help would be greatly appreciated.

This may not be the best way but it works. Basically calculate a Y position for a TEXT plot and don't use the seglabel or datalabel options.

data work.myattrs;
length value fillcolor $12;
show='AttrMap';
id="jrc_ID";
value=11; fillcolor='red';textcolor='yellow'; output;
value=12; fillcolor='yellow';textcolor='red'; output;
value=13; fillcolor='green';textcolor='purple'; output;
value=14; fillcolor='blue';textcolor='orange'; output;
value=15; fillcolor='black';textcolor='white'; output;
value=16; fillcolor='cyan';textcolor='black'; output;
run;


proc summary data=sashelp.class nway;
class age;
var weight;
output out=class mean=;
run;
data class;
   set class;
   y= weight/2;
   text = put(weight,best4.);
run;

proc sgplot data=class dattrmap=work.myattrs;
vbarparm category=age response=weight / group=age  dataskin=matte attrid=jrc_ID ;
text x=age y=y text=text/ attrid=jrc_ID group=age;
run;

Calculating a segment label location for stacked elements may be tad trickier but the general approach works. I'm not sure if a later version has more options for segment text in either the dattrmap set or options.

This is doing exactly what I need it to do.

Thank you.
