Scatterplot Help: Graphing A Response Variable From Multiple Groups Over Time SAS University Edition

Hello,

 

I need a bit of help creating a graph in SAS University Edition. 

 

What I am trying to do is create a scatterplot where x=response variable, y=time with 4 levels of a grouping variable. Each level of the grouping variable contains 10-12 observations at each time point. I am trying to display all observations across time, but with the observations from each group seperated in space on the chart. (I apologize if this description is lacking).

 

Here is what I have so far:

 

proc sgplot data=plin2bodycomp_organized;
      scatter x=time y=weight / jitter group=Treatment_Group;
run;

/*** weight= Response Variable, Treatment_Group= Group Variable **/


/* Note that jitter does technically separate the values in space, but it is not organized by group */

I have also attached the graph it produced:

In R, creating the seperation I am looking for can be dong with the "position dodge" arguments when using the ggplo2 package (example below). Does SAS have anything similar?

Thank you for your time and your help.

On your SCATTER plot statement, add GROUPDISPLAY=CLUSTER and see if that works for you.

 

Thanks!

Dan

Thanks, DanH, that worked!

Is there any way to change the distance between the groups clusters?

 

Also, in a related note, are there any highly recommended resources for graphing in SAS? I am new to SAS Graphing and would appreciate a solid reference.


Thanks

Use the CLUSTERWIDTH option on the SCATTER statement. It is a value between 0 and 1. The default is something like 0.85. In your case, you want to shrink the cluster width, so try a value of 0.4.

 

As for a graphics reference (shameless plug alert :-)).... If you are working with the SG procedures, Sanjay Matange and I worked on book that should get you up-and-going with the procedures quickly. Check it out and see what you think...

Thanks again, DanH. This is exactly what I was looking for. 

 

Thanks also for the recommendation, I appreciate it.
