Mixed cross-sectional/longitudinal line graph

Postby NicoleAnderson » Fri Feb 20, 2015 4:46 pm

Hi all,

I have brain volume data from a large number of people of different ages who were all scanned twice at least a year apart. So, for example, one person was 29.7 years old at time 1 and 34.1 at time 2; another person was 68.2 years old at time 1 and 69.5 at time 2. I want to plot brain volume (y-axis) by age (x-axis) for each person, with a line connecting the two volumes for each person.

Does anyone know how to do this?

Cheers,

Nicole Anderson
