Multiple line graphs in one graph.

[Barkamih]

Hi Guys,

I'm using  the following code for my data to preset 4 groups in one graph, as you see this code can do what I'm looking for but the only issue is that I couldn't make the line graphs in different looking such as, continues dots, not continues line or whatever any differentiation to make line different for each group.

by default, these graphs are in different colours, but different colures do not work for black and white printing.    

I'll be happy for your help

proc nlin data = milkno method = marquardt;
parms A = 15 B = -0.19 C = 0.0012 ;
by pr ;
model TEST_DAY_milk_kg = A * Time **b * exp(-C*Time);
output out = Fit predicted = pred ;
symbol1 interpol= join value = star color= black;
symbol2 interpol = none value = none color = red;
run;
QUIT;

proc sort data=fit;
by time;
RUN;

proc sgplot data=fit;
series y=pred x=time / group=pr;
xaxis values=(1 to 12 by 1);
yaxis values=(0 to 40 by 5);

run;

With PROC SGPLOT, you need the ATTRPRIORITY=NONE option and the STYLEATTRS statement. Example:

ods graphics/attrpriority=none;
proc sgplot data=sashelp.stocks(where=(stock='IBM' or stock='Microsoft'));
	styleattrs datacontrastcolors=(black black) datalinepatterns=(dot solid);
	series x=date y=open/group=stock ;
run;

The list of line patterns is here: https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.4&docsetId=grstatproc&docsetTarget=p...
