sgplot: change group colour and line style

lone0708 — Tue, 23 Aug 2022 10:36:12 GMT

Hello all,

I am doing a survival curve using proc sgplot and the group statement. I have a total of 8 groups. I need some of the groups to have dotted lines and some of them to have full lines and specify every groups colour.

How to put it into the following code?

proc sgplot data=abc2;
series x=weeks y=SURVIVAL1 /group = exp_event;
run;

For full control of the attributes try a Discrete Attribute Map .

You can use the STYLEATTRS command in PROC SGPLOT

Example

styleattrs datacontrastcolors=(orange cyan CXFF0000) 	
    datalinepatterns=(dot solid longdash 26);

Experiment to find what works for you.

@PeterClemmensen is correct. You' will want to use an attributes map. Here is a simple example using a SERIES plot below:

data attrmap;
retain ID "myid" nocase "true";
input value $ linecolor $ linepattern $;
cards;
F   pink   solid
M   blue   dash
;
run;

proc sgplot data=sashelp.class dattrmap=attrmap;
series x=name y=weight / group=sex attrid=myid;
run;

Thank you for your answer 🙂
I have tried to make the attribute map (please see attatched photo), but the colours are not at all corresponding. Do i miss something in the code?

The column names in an attributes map are reserved keywords, so they must be spelled as they are expected. In your screenshot, you have spelled the expected "fillcolor" with the alternate "fillcolour" spelling. Also, for a series plot, you should be using "linecolor" instead of "fillcolor".
