What can I do so that M is a blue dashed line, F is a red dashed line, and N is a solid black line?
In addition, how to set the style of the line?
Thank you very much for everyone’s helpful replies.
Here is my code and a picture of the result.
proc sgplot data=a;
title "Figure 3";
vline pro / response=rt stat=mean markers
group=vio lineattrs=(thickness=4px);
run;
