Less then or equal sign in PROC SGPLOT

[Chaupak]

Hi, I was trying to draw a series plot by group and display the every group's name in the legend. One of the groups represents a range "<= xx mg". However, I want its label to be displayed as the sepcial character of less than or equal to sign instead of the combination of "<" and "=" in the plot. This is the sample data and code:

DATA plot;
INPUT year value group$;
CARDS;
1 10 <=50
2 15 <=50
3 20 <=50
4 25 <=50
5 30 <=50
1 10 >50
2 30 >50
3 50 >50
4 70 >50
5 90 >50
;

proc sgplot data=plot;
    series x=year y=value / group=group;
run;

I've tried to replace with "(*ESC*){unicode '2264'x} 50" in the dataset, but it didn't work in PROC SGPLOT. Is there any way to display the right special character in the plot?

proc format;
   value $group '<=50' = "(*ESC*){unicode '2264'x} 50";
   quit;
proc sgplot data=plot;
    series x=year y=value / group=group;
    format group $group.;
run;

Thank you so much! It's perfect.
