Hi,   I am trying to create series plot using SGPLOT. The assumptions are that lines should be dash when result is collected before starting point (0 on x-axis) and solid when result is collected after starting point. I should draw as many lines as subjects in the input dataset and these lines should be colored depending of subject age (3 groups - 3 colors). I used two approaches but not get 100% what I want.   The first one is to call series statement two times - one for data pre and second for data post. Then use grouplc for assigning correct colors. It works almost fine but there is a break between dashed line and solid line when plot passes 0 point. The code which I am using is: title "Figue 1.1"; footnote1 j=l "This is a test series plot"; proc sgplot data=plot_data3 dattrmap=myattrmap; series x=x_pre y=y_pre / name="plot1" group=subj groupdisplay=overlay grouplc=fl_a lcattrid=myid2 lineattrs=(pattern=dash); series x=x_post y=y_post / name="plot2" group=subj groupdisplay=overlay grouplc=fl_a lcattrid=myid2 lineattrs=(pattern=solid); xaxis label="x-axis"; yaxis label="y-axis"; legenditem type=line name="dash_line" / lineattrs=(pattern=dash color=black thickness=1.0pt) label="Pre-Trt"; legenditem type=line name="solid_line" / lineattrs=(pattern=solid color=black thickness=1.0pt) label="Post-Trt"; legenditem type=line name="age1" / lineattrs=(pattern=solid color=green thickness=1.0pt) label="Age <= 7"; legenditem type=line name="age2" / lineattrs=(pattern=solid color=blue thickness=1.0pt) label="7 < Age <= 14"; legenditem type=line name="age3" / lineattrs=(pattern=solid color=red thickness=1.0pt) label="Age > 14"; keylegend "age1" "age2" "age3" "dash_line" "solid_line" ; run; Result: The second approach is to call series three times - one for each age group and use grouplp= but it is not working. I get only solid lines with this. title "Figue 1.2"; footnote1 j=l "This is a test series plot"; proc sgplot data=plot_data3 dattrmap=myattrmap; series x=x_g y=y_g / name="plot1" group=subj groupdisplay=overlay grouplp=fl_p lpattrid=myid1 lineattrs=(color=green); /* grouplp not working */ series x=x_b y=y_b / name="plot2" group=subj groupdisplay=overlay grouplp=fl_p lpattrid=myid1 lineattrs=(color=blue); /* grouplp not working */ series x=x_r y=y_r / name="plot3" group=subj groupdisplay=overlay grouplp=fl_p lpattrid=myid1 lineattrs=(color=red); /* grouplp not working */ xaxis label="x-axis"; yaxis label="y-axis"; legenditem type=line name="dash_line" / lineattrs=(pattern=dash color=black thickness=1.0pt) label="Pre-Trt"; legenditem type=line name="solid_line" / lineattrs=(pattern=solid color=black thickness=1.0pt) label="Post-Trt"; legenditem type=line name="age1" / lineattrs=(pattern=solid color=green thickness=1.0pt) label="Age <= 7"; legenditem type=line name="age2" / lineattrs=(pattern=solid color=blue thickness=1.0pt) label="7 < Age <= 14"; legenditem type=line name="age3" / lineattrs=(pattern=solid color=red thickness=1.0pt) label="Age > 14"; keylegend "age1" "age2" "age3" "dash_line" "solid_line"; run; Result: I can "cheat" in case of first option and prepare data that last row of pre group is the same as the first row of the post group but doing this can lead to situation that I have solid line before 0 point on x-axis and it will be confusing. Is there any better solution for this problem, please?   Below the rest of the code (data preparation). title; footnote; data plot_data; do i=1 to 3; subj="S"||strip(put(i,z3.)); if i=1 then age=6; if i=2 then age=12; if i=3 then age=18; age=22*ranuni(22)+3; do j=1 to 50; x=15*ranuni(22)-5; /* (b,a+b) */ y=99*ranuni(22)+1; output; end; end; attrib x label="AYEAR" y label="REUSLT"; drop i j; run; data plot_data2; set plot_data; length fl_p $5. fl_a $10.; if x < 0 then fl_p="PRE"; if x > 0 then fl_p="POST"; if age < 7 then fl_a="GREEN"; else if 7 <= age < 14 then fl_a="BLUE"; else if age > 14 then fl_a="RED"; fl_all=compress(cat(fl_p,"_", fl_a)); run; data plot_data3; set plot_data2; if fl_p="PRE" then do; x_pre=x; y_pre=y; end; if fl_p="POST" then do; x_post=x; y_post=y; end; if fl_a="GREEN" then do; x_g=x; y_g=y; end; if fl_a="BLUE" then do; x_b=x; y_b=y; end; if fl_a="RED" then do; x_r=x; y_r=y; end; run; proc sort data=plot_data3; by subj x; run; data myattrmap; length id $ 10 value $ 10 linecolor $ 9 linepattern $ 9; input ID $ value $ linecolor $ linepattern $; datalines; myid1 PRE black dash myid1 POST black solid myid2 GREEN green solid myid2 BLUE blue solid myid2 RED red solid ; run; Thanks in advance for your help.
