# Add number of observation to a plot

Now I have a code that plots the cumulative return of firms from 1994 till now but I want to add number of observation that used to calculate the cumulative return at each time point. Some sample code:

``````options nodate orientation=landscape;
goptions device=pdfc; /*Plot Saved in Home Directory*/
ods pdf file=&locationin;
axis1 label=(angle=90 'Value of \\$1 invested in a portfolio');
axis2 label=('Date');
symbol1 interpol =join ci =green w = 3 co =green;
symbol2 interpol =join ci =blue co =blue value =star;
proc gplot data =work.CumRet;
Title &titlein ;
plot top*date= 1 bottom*date= 2 / overlay legend vaxis=axis1 haxis=axis2;
run;quit;ods pdf close;``````

Or, if my description is not clear enough, generally, how could I add the number of observation at each point of a curve plot? Given I have the number of observation variable.

## Re: Add number of observation to a plot

First, move to proc splot and GTL, it is far more powerful, gplot is very old.

Second, take a look through this blog which gives examples for almost any graph you want, and you will find examples of what you want:

What you want is datalabel:

With Proc Gplot, annotate data set.
