Irin,

Though I totally agree with Peter about pie plots, it is interesting to
see how SAS combines donuts and pies for a tasty snack .. perhaps this is
a start (after adjusting your goptions), but there are a multitude of
better ways for comparing the percent distribution of two types of
percents for categorical, namely where the pie slices line up showing
percents for each level race can be down-right confusing.

data pdt(keep=race employees members)
     plt(keep=grp race perc);
INPUT Race $16. Employees Members ;
OUTPUT pdt;
grp='Employees'; perc=Employees; OUTPUT plt;
grp='Members';   perc=Members; OUTPUT plt;
cards;
White            60 40
African American 15 20
Hispanic         17 24
Asian             6 10
Other             2  6
;

proc sort data=plt ; by grp race; run;
proc print data=plt NOObs n; run;

proc print data=pdt NOObs n; run;

goptions reset=all Hsize=10 in Vsize=8 in htext=2;

legend1 position = (right middle outside) label=(h=2) value=(h=2) across=1
down=5;
proc gchart data=pdt ;
pie race / percent=inside sumvar=employees radius= 20 noheading coutline=
none name="pie" legend=legend1;
donut race / percent=outside sumvar=Members radius =30 donutpct=60
noheading coutline=black name="don" legend=legend1;
TITLE;
run; quit;

proc greplay igout=gseg tc=sashelp.templt nofs;
template whole;
treplay 1:pie 1:don;
run;
quit;

* a vertical bar graph that allows side-by-side comparisons of percents by
levels of race is much clearer, if that is your objective;

axis1 length = 12 in value=(h=1.5) ;
axis2 length=6.75 in value=(h=2) minor=none  label=(a=90 h=2.5 'Percent');
proc gchart data=plt;
vbar grp / Noframe sumvar = perc coutline=black group=race space=3 width=8
gspace=5 maxis=axis1 raxis=axis2;
TITLE;
run; quit;

Graphics: inner & outer Doghnut pies for percentage distribution
(comparison)

For the comparison purposes I need to create  SAS code for two Doughnut
Pies Clustered by Race based on the data set. For ex:

Race                                   Employees Percent           Members
Percent

White                                    60
     40
African American                  15                                    20

Hispanic                                17
           34
Asian                                      6
      3
More races                             2
        3


The inner Dougnut pie  (like a ring) should represent Employees’ race
percentage distribution while an outer Doughnut  pie should show members
race percentage distribution. The inner one does not have breaks at all
while an outer does as it is located around the inner one

I also need a legend. For ex

Blue color box-White
Pink                 -African American
Green             -Spanish
Purple            -Asian
light blue       More  races

Could you give me a hand with SAS  9.2 code?

Thank you in advance,


Irin
