Martin

to make ma point clear, I'll build on your example:

**************
clear
vers 11

set obs 4
gen id=_n
expand 10
bys id: gen time=_n
gen x=runiform()
xtset id time
replace x=. if runiform()<.3

xtline x, overlay cmissing(n) name(mygr, replace)
**************

the last line returns an error message. the two options -cmissing(n)- and
-overlay- do not seem to get along. 

-xtline2- suffers from the same problem. Following up on the above example:


**************
version 10.1
xtline2 x, overlay cmissing(n) name(mygr, replace)
**************

returns the same error message.

My conclusion is that there is a problem with -xtline- in need of
consideration.

Personally, I also do not like to be forced to switch between -xtline- and
-xtline2-, depending on the Stata version I am (or my co-author is) using.
