Dear Nick and Sergiy

Im sorry, to me (sitting and working with the data) what i wanted was obviouse. But seeing only have the Info given to you, to try to help i will elaborate:

 On my X axis i would like scan. 
On my Y axis i would like tTbN. 

Scc i ment ssc
Lineplot was autocorrect for linkplot
http://www.stata.com/statalist/archive/2003-07/msg00194.html

I am not sure but some patients tend to have lower values tTbN at scan 2 and some tend to have higher. I afraid that connect(direct) does not take this into account and i need the connecting lines to be from PatNo to the same PatNo to show what i said before. 

Hope this was the information you needed. 

Mvh Lars Folkestad
