Due to user complain the difficulty about understanding the meaning of box plot, I ‘translate’ the box plot to histogram. Why the chref=green and whref=3 don’t work in proc univariate? Is there better way to do this?
/*Generate box plot: options must have*/ ods pdf file="&pdfout\box.pdf" notoc; title; ods graphics / reset=all height=2.7 in width=4.3in; ods graphics on / border = off; ods graphics on / imagemap=on; Title1 h=1.4 j=c font=Arial bold "Age Summary - box"; proc sgplot data=class; hbox age; refline &ag1 /axis=x lineattrs=(color=green thickness=3) label=("&nm1: &ag1") labelloc=inside; run; quit; ods pdf close; /*Generate histogram*/ ods pdf file="&pdfout\hist.pdf" notoc; title; ods graphics / reset=all height=2.7 in width=4.3in; ods graphics on / border = off; ods graphics on / imagemap=on; Title1 h=1.4 j=c font=Arial bold "Age Summary - hist"; proc univariate data=sashelp.class noprint; histogram age / midpoints = 10 to 20 by 1 rtinclude href=&ag chref=green whref=3 hreflabel="&nm1: &ag1" outhistogram = OutMdpts; run; quit; ods pdf close;
Those options on UNIVARIATE might only work with GRSEG-based output. SGPLOT also has a HISTOGRAM statement, and you can overlay REFLINEs behind or in front of the histogram. You can also control the attributes of the REFLINEs. Here is a simple example:
proc sgplot data=sashelp.heart;
histogram cholesterol;
refline 200 / axis=x lineattrs=(color=red thickness=2);
refline 300 / axis=x lineattrs=(color=green thickness=2);
run;
Thank you very much. This refline seems a little bit of misleading. What I really need is an indicator to highlight the cross point of age and percent for a student, for example to indicate Carol belongs to 20% distribution group, not necessary a refline. The indicator label should be like “Carol: 14”. Welcome suggestion or creation.
proc sql noprint; select name, age into :nm, :ag from sashelp.class where name="Carol"; quit; %let ag1=&ag; %let nm1=&nm; proc sgplot data=sashelp.class; histogram age ; refline &ag / axis=x label ="&nm1: &ag1" labelloc=inside lineattrs=(color=green thickness=2); run;
I'm not quite sure of what you need. Can you post a picture?
It was so nice to meet you in person around the SAS Global Forum 2018. I agree with your explanation, i.e., the 'translation' doesn't work well. Thank you. By the way the supper demo is great, and I am thinking to attend in 2019. Hopefully see you there!
