SGPLOT Legend with One Variable Repeated Twice

[Junyong]

I want to draw a time-series using SGPLOT. I want to display plane and log versions together because the series is exponential. The only problem is the legend, which repeats the name x just twice. Can I give separate names in this case? The following is the code.

data have;
do t=1 to 5000;
if t=1 then x=1;
else x=x*(1+0.1/12+0.05/sqrt(12)*rannor(1));
output;
end;
run;
ods listing gpath="!userprofile\desktop\";
proc sgplot;
series x=t y=x;
series x=t y=x/y2axis;
xaxis display=(nolabel);
yaxis display=(nolabel);
y2axis display=(nolabel) type=log;
run;

Thanks for your help.

From SAS 9.4M5, you can do something like this

data have;
do t=1 to 5000;
if t=1 then x=1;
else x=x*(1+0.1/12+0.05/sqrt(12)*rannor(1));
output;
end;
run;

proc sgplot;
series x=t y=x;
series x=t y=x/y2axis;
xaxis display=(nolabel);
yaxis display=(nolabel);
y2axis display=(nolabel) type=log;

legenditem type=line name='x1' / label='x' lineattrs=GraphData1;
legenditem type=line name='x2' / label='x (Log)' lineattrs=GraphData2;

keylegend 'x1' 'x2';
run;

Result:

Or you can do this

proc sgplot;
series x=t y=x / legendlabel='x';
series x=t y=x / y2axis legendlabel='x (Log)';
xaxis display=(nolabel);
yaxis display=(nolabel);
y2axis display=(nolabel) type=log;
run;
