Change line from solid to dash

kuuz — Sun, 06 Oct 2019 19:18:18 GMT

Hello,

I have school enrollment data for two periods (1, 2) and whether they received treatment (0,1). The data is attached and the graph that I produced are attached. I wanted to show the treatment effect using the parallel trend. My supervisor wants me to change the control group line (given by the blue to black dots and solid black line for the treatment given by the red). I copied the program from online and played with it until i got it this close. However, I don't know how to do what my supervisor advised me to do. Any help will be welcomed:

proc sgpanel data=work.data1 ;
panelby period /uniscale=row;
title "Early Adoptors vrs late Adoptors Before t=2007";
reg y=avg_overall x=year /group=treatment_status ;
run;

Add option lineattrs=(pattern=shortdash) to the reg statement.

Thank you for the suggestion.So I did run your suggestion in the program below. It changes both lines to short dashes. I want only the blue line to be dashes while maintaining solid line for the red. Thank you again.

proc sgpanel data=work.final3b1 ;
panelby period /uniscale=row;
title "Early Adoptors vrs late Adoptors Before t=2007";
reg y=avg_overall x=year / lineattrs=(pattern=shortdash) group=treatment_status ;
run;

Try a STYLEATTRS options instead of lineattrs or list multiple patterns if you have multiple lines, they are applied in order of your groups, alphabetically I believe.
