The link above shows what I'd like to do, but I can't figure it out. I'd like two trend lines for two groups on one graph (arm span by height for the sexes separately). This is one of my favorite analyses (ANCOVA) and my class will learn much more if I can show them their data properly labelled and organized. I can make a regular scatterplot with a single group, so I only need help making the two groups with different color points and separate lines.
Can anyone help? I'm running the latest version of OpenOffice on a new mac powerbook running 10.8.
Thanks in advance.
