st: coding a categorical variable to a % continuous variable

[Suzy <scott_788@wowway.com>]

Hello,

I have a dichotomous variable (0=no ; 1=yes) that I would like to use in 
a scatter plot on the y axis as a continuous variable  as a  % variable.

For example:  the x axis could be age and the y axis could be % smokers.

Can anyone help with this ?

Thank you.
Suzy
