Thanks, I appreciate your help. I created the
variables, scatter does not help me however graph
generated by command "serrbar" is something i want. 

serrbar does not allow me to plot it over more then
one categorical variable. 

I have to plot mean blood flow in three age groups at
two different temperatures (26 & 35oC) and for both
males and females. With "graph box" I can specify
catergorical variables by writing "over" but serrbar
does not work same way. Does it mean that I have to
create six different mean sd and use serrbar command
to plot them in one graph. 

Please advice 

Thanks in advance
