Hi, I am trying to plot the mean for each group over time 

I have calculated the mean for each group at each time ( time from 1 to 7 i.e seven time points ) 

 

my output look like this 

Capture555.PNGso I want to plot the group 1 with the first row( mtime1 to mtime7 over seven time pionts)

and same for group 2 with the second row and same with group 3 

 

I tried to do something like that but it did not work

proc means data=insulin3 mean; by group;
  var time1 time2 time3 time4 time5 time6 time7;
  output out=new mean=mtime1 mtime2 mtime3 mtime4 mtime5 mtime6 mtime7;
run;

proc print data = new;
run;

proc sgplot  data=new;
 scatter x=group y=mtime1;  
 run; 

I used sgplot because proc gplot is not available in SAS studio. 

thanks for your help

You need to change your data structure. If it's in a long format this is a trivial exercise. 

Reformat your data to have:

 

Group Time Measurement

1 1 XX

1 2 XX

1 3 XX

...

2 1 XX

2 2 XX

..

4 7 XX

 

 

Then your graphing statement becomes:

 

proc sgplot data=transposed;
series x=time y=measurement / group=group;
run;
