Horizontal Reference Line with BOXPLOT

Doug____ — Mon, 27 Feb 2017 18:00:48 GMT

When using the vref = 0.0 and lvref = 2 options in SAS 9.4, the line type does not change. Is there another option I need to use. I tried several lvref values - same result - only a solid line.

Are you talking about PROC BOXPLOT? Please post the code that you are using.

Also, are you trying to use traditional graphics or ODS statistical graphics? The LVREF= option is not valid for ODS graphics. If you want traditional graphics, put

ods graphics off;

prior to the call to PROC BOXPLOT.

ODS Graphics - cannot use non-ods for my outputs

proc boxplot data = xxx;
plot aval*group1/vaxis= -0.6 to 1.0 by 0.2 boxstyle=schematic odstitle = none vref = 0 lvref = 3 ;
label group1="Dataset";
label aval="PARAMX, Mean ±1 SD"

run;

As I said, you can't use the LVREF= option with ODS graphics.

However, you can create this box plot is PROC SGPLOT. The REFLINE statement give you complete control over line patterns, colors, and thickness

proc sgplot data=sashelp.cars;
 vbox mpg_city / category=origin;
 refline 20 / lineattrs=(pattern=dot);
run;
