Is there a way to dynamically change the reference line by group? I know the BY command to draw a graph for each group but what about in each of those graphs, we have a different refline too?
Here's one way to do it, by adding some extra obsns to the dataset ...
proc sql noprint;
create table avg_data as
select unique sex, avg(height) as avg_height
from my_data
group by sex;
quit; run;
data my_data; set sashelp.class avg_data;
run;
proc sort data=my_data out=my_data;
by sex;
run;
title "Class Data";
proc sgplot data=my_data uniform=scale;
by sex;
scatter y=height x=weight;
refline avg_height / label;
run;
thanks. This works very well, except that I have 2 reflines which are dates. Instead of date, I would want to label it 'IN' and 'OUT' for the first and second refline, respectively. How could I achieve this? I tried this code but it does not work:
proc sgplot data=Sp500_in_out_sample2;
by stock;
series x=date y=price;
refline date_in / axis=x label='in';
refline date_out/ axis=x label='out';
run;
When you use variable-based REFLINEs, the LABELs must also be variable-based. Just create additional columns containing your "in" and "out" labels (e.g. inlabel and outlabel), and do the following:
proc sgplot data=Sp500_in_out_sample2;
by stock;
series x=date y=price;
refline date_in / axis=x label=inlabel;
refline date_out/ axis=x label=outlabel;
run;
Hope this helps!
