Dear Newsgroup,

I still sit on the following problem. This is my data:

data test;
        INPUT obs cum_data;
cards;
1 12864
2 26642
3 35302
4 49776
5 66605
6 85682
7 105312
8 130413
9 161525
;
run;

Now I want to make a barchart of this data what actually is not the
problem. The problem is that I want to overlay a Gompertz curve where I
don't know how to estimate it. The drawing should later be done with
prog greplay. But how to get the curve?

Can anyone provide with an example of code that helps to solve my
problem?

Thanks a lot - Antje
