Box Plot

marianhabesland — Tue, 28 Nov 2017 20:45:44 GMT

I am creating a vertical box plot and want to add some specific features. So far I have produced this code that creates the general structure that I want.

title "Diastolic Blood Pressure by Ethnicity/Race Group" bold;
proc sgplot data = HypAnl.HypPrimanl;
vbox DBP / group = EthRaceCd ;
run;

I now want to add some specific features, but am unsure exactly where in code they actually go. For example, I want a reference line called "Hypertension Threshold" that runs at 90 on the Y-axis. Where in the code do I add these kind of features?

Just add more statements. In particular, put a REFLINE statement after the PROC statement.

Statements listed first get displayed first.

title "Diastolic Blood Pressure by Ethnicity/Race Group" bold;
proc sgplot data = HypAnl.HypPrimanl;

refline 90;
vbox DBP / group = EthRaceCd ;
run;

This will make the reference line draw behind the boxes. Move the REFLINE statement after the VBOX statement if you want them drawn in front of the boxes. There are a number of options on the REFLINE statement to enhance its appearance.

Hope this helps!
