How to display the value from REFLINE in PROC SGPLOT.

Hi there,

I’m creating a plot (i.e. empirical density function) and I’m including a vertical line corresponding with a the cut-off value '&max' in the REFLINE statement (see code below).

Nevertheless, the actual value is not displayed at the bottom of the line. Can you please let me know how can I do that?

Thanks a lot,

A.G.

proc sgplot data=dat cycleattrs ;

density &var/ LINEATTRS=(color=daolg)type=kernel(c=25) scale=density freq=&weight legendlabel="prior";

xaxis label="&label" min= 0 max=&mx;

yaxis label='Empirical density function(EDF)';

*Inserting cut-off values as vertical lines;

refline &max / axis=x lineattrs=(thickness=3 color=darkred pattern=dash)

label=("UL");

run;

You have not provided anything that might hold the value to the Label

If &max is a single value then add that to the Label ="UL &max"

If your &max is more than a single value then you need to describe things a bit better and may be better off adding some records to the data set with the values and having the variable containing the Refline values instead of a list, then use that or a variable build to hold the desired text in the Label= option.

Hi BallardW,
Thanks for your recommendation. &max is indeed a single value. I thought about that obtion, but I rather have the value displayed at the bottom of the X axis and at the top the label 'UL'.

As far as I know you only get one label position per refline. But I bet if you add a second Refline statement with the LABELPOS=max (this is a standard parameter NOT your macro variable) and Label="&max" that you get what you want.

You are drawing the same line twice with two different labels.

That worked perfectly.
Thanks again!
