Positioning labels on Refline PROC SGPLOT

Jepi — Mon, 13 Nov 2023 22:08:11 GMT

Hi I am using PROC SGPLOT and have two reference lines (one at 40 and one at 50). Refline 40/axis=y Label = “Midterm” labelloc=inside labelpos=min;
Refline 50/axis=y Label = “Second Semester” labelloc=inside labelpos=min;

The problem I'm running into is the labels are overlapping. I want to position the label at 40 below the reference line and the label at 50 above its reference line.

Easiest is just to change the LabelPos to one of of those to be MAX.

If you want to explicitly control the location of text I suggest adding observations to your data set to allow use of a TEXT plot statement with the X, Y location and a variable to hold the text. Then do not include a label on the line at all. The Text plot would allow a few more options for displaying the text.

Thanks! With setting one to MAX and the other to MIN. The 50 refline still runs through the 40 refline label.

Does X and Y have to be numeric?

Now we are at the point where you should provide an example of the data set you are using for proc sgplot and the entire code of the Sgplot used.

Refline values do not have to be numeric but if you are using a character value for the line that it is not one of the actual values results are at best unpredictable and likely to not appear at all.

Example of a not very useful graph but shows use of text values for refline when the axis is character:

Proc sgplot data=sashelp.cars;
   scatter x=make y=type;
   refline 'Isuzu' /axis=x  ;
   refline 'Sedan' /axis=y ;
run;
