Legend texts are not what I expected

[Smurf]

The legend text are not what I defined in Format. Does any one know why? The Diabetes_cat variable only has 1, 2, 3, but the legend has 1.2 and 1.8

proc format library=data;
	value Diabetes_cat
		1='Normal'
		2='Prediabetic'
		3='Diabetic'
	;
run;

legend2 label=('Diabetes')
;

proc gchart data=data.freq4chart2;
	donut Diabetes_cat / sumvar=count
		PERCENT=INSIDE
		subgroup=AgeGroup2
		donutpct=20 
	noheading
		legend=legend2;
run;

[Smurf]

proc format lib=data;
value site
1=Sydney
2=Atlanta
3=Paris
;
run;

data totals;
	length dept $ 7 ;
	input dept site quarter sales;
	format site site.;
datalines;
Parts 1 1 7043.97
Parts 2 1 8225.26
Parts 3 1 5543.97
Tools 1 4 1775.74
Tools 2 4 3424.19
Tools 3 4 6914.25
;


legend1 ;

proc gchart data=totals;
	format sales dollar8.;
	donut site / sumvar=sales
subgroup=dept 
donutpct=30
label=("All" justify=center "Quarters")
noheading
legend=legend1;
run;

Another Example already rebuilt such result.

Add the DISCRETE option to the DONUT statement and let me know if you get the expected results

Yes, it gave the expected result.
Thank you so much!
