Assigning colors and patterns to each category of a variable in sgplot

[Novice_]

Hello,

I am using the following code:

ods graphics on;
proc sgplot data=numbers noautolegend;
series x=time y=rate / group=group_cat;
keylegend / title='Group Categories' position=right;
xaxis grid label="Week";
yaxis grid;
run;
ods graphics off;

and the plot I get is below:

I need help with changing the patterns, thickness and colors of each line in this plot. The variable group_cat has 4 categories. Is it possible to do it within this code or do I need to create 4 variables representing the 4 categories and add 4 series statements? Thank you.

You can use the STYLEATTRS command with the DATACONTRASTCOLORS= option in PROC SGPLOT.

Or you can also assign colors via a discrete attribute map: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.4/grstatproc/n18szqcwir8q2nn10od9hhdh2ksj.htm

Thank you so much.
Both options work. I tried both and found that the datacontrastcolors gives less control compared to the other one.
Best Regards

data dattrmap;
retain ID "myid";
input value :$20. linethickness  linecolor $ linepattern $;
datalines;
IBM    2  orange  solid
Intel    4    blue    dot
Microsoft  8    red    longdash
;
run;


proc sgplot data=sashelp.stocks dattrmap=dattrmap;
where date between '01JAN02'd and '30DEC02'd;
series x=date y=close/group=stock attrid=myid;
run;

Thank you.

I have incorporated your code as following:

data dattrmap;
retain ID "myid";
INPUT value :$20. linethickness linecolor $ linepattern $;
datalines;
One 2 red soild
TWO 2 red dash
THREE 2 blue solid
FOUR 2 blue dash
;
run;
ods graphics on;
proc sgplot data=numbers dattrmap=dattrmap;
where time between 0 and 53;
series x=time y=rate / group=group_cat attrid=myid;
keylegend / title='Group Categories' position=right;
xaxis grid label="Week";
yaxis grid;
run;
ods graphics off;

However, this gives me an error: ERROR 772-580: Syntax error: expecting a constant or a dynamic.

I think I got it. Perhaps I should have added the ID in the input statement.
Thanks a lot.
