Spaghetti plot with different markers

 

I am trying to create a spaghetti plot using PROC SGPLOT.

I am using Subject ID as the group variable. I want to display

different markers for each subjects. In the current plot all the subjects have

same markers. I would different markers. How can this be achieved ?

Here is the very simple starting code...

 

proc sgplot data = lab ;
series x = weeks y = lbstresn / markerattrs =(symbol=circlefilled )group = subjid ;
yaxis type = log logstyle = logexpand display = all;
xaxis values= (0 to 30 by 1 );
run;

Re: Spaghetti plot with different markers

What version of SAS are you running?  In SAS 9.4m2 you can use the GROUPLC=, GROUPLP=, GROUPMC=, and GROUPMS= options to specify the colors and patterns of lines and the colors and symbols of markers, respectively.

 

For your example, I think you can write:

series x=weeks y=lbsresn / group=subjid groupms=subjid markers;

 

Of course, if you have more than about 20 subjects, you will run out of markers.

Thank you. GROUPMC options works.

Re: Spaghetti plot with different markers

Great! Just to be clear, GROUPMC= changes the color. GROUPMS= changes the symbol.
