Plot of means

Hi,

I am doing project about how affect meals on blood glucose.

I have following code:

DATA glucose;
	infile 'E:\GLUCOSE.DAT' EXPANDTABS;
	input id g1-g10;
	tm=int((_n_-1)/6)+1;	
run;


DATA missqlucose;
SET glucose;
if g9=-1 then g9=.;
if g10=-1 then g10=.;
run;


PROC plot data=missqlucose (firstobs = 1 obs = 6);
run;

DATA glucose1;
set missqlucose (firstobs = 1 obs = 6);
run;

PROC TRANSPOSE data=glucose1 out=gtrans1 name=time prefix=p;
VAR g1-g10;
run;

PROC PRINT DATA= gtrans1;
run;

Now i need to make one plot of the separate tm class means across gk, where k is from 1:10 (in other words, for g1 g2 g3....g10)

P.S. i attached fili that in infile (see above), just change *.txt to *.dat

Hello,

If you just want the mean then you can use the vbar statement in Proc SGPLOT. Below is the code that you can use to get this. I wasn't sure if you wanted means of g1-g10 or means of p1-p6, but you can adjust the code accordingly.

PS, it may be useful to see the variation in the data, so you could also look at doing a boxplot. or plotting the mean and confidence intervals.

proc sort data = gtrans1;
by time;
run;

proc transpose data = gtrans1 out = gtrans_stacked;
var p1 - p6;
by time;
run;

proc sgplot data = gtrans_stacked;
vbar _NAME_ / response = COL1 stat= mean;
run;

Hi,

Thank you for code. How to put values of means next to each bar on that graph?
