when I plot twoway (scatter HbL HbH if sex==1) (scatter HbL HbH if
sex==2) I expect to get an overlaid plot with corresponding HbL & HbH
having one symbol if sex==1 and another symbol if sex == 2. I get
different symbols, but in the legend box I get a blue diamond signifying
HbL and a brown diamond signifying HbL. That's right, both signify HbL
and neither one signifies sex, which I expected. What is going on? What
am I doing (or interpreting) wrong?
Many thanks.
