The following command works fine.
twoway (scatter CEC week), by (Group) yscale(log)
(Group takes on three values.) But when I attemmpt to add "by options" I
get errors:
. twoway (scatter CEC week), by (Group, total) yscale(log)
) required
r(100);
Also when I attempt to use the syntax in the Stata Release 10 Graphics
manual (page 406), I get an error:
. scatter CEC week, by (Group)
option by() not allowed
r(198);
although the yscale option works.
. scatter CEC week, yscale(log)
I am using
