Thanks for this. Note that the code else { replace `coefficient'=. in `num' } replaces missings with missings, to no useful purpose. On your question, I am guessing that you want the items of `eqlist' to end up as value labels. tokenize "`eqlist'" forval i = 1/`eqnum' { local call `call' `i' "``i''" } ... xla(`call') would be one way to do that. Nick n.j.cox@durham.ac.uk Roy Wada Thanks, Nick. Dropping variables will not bite since -preserve- is applied, but it is a poor programming style. A better way is to give labels to temp variables, which would have prevented them from showing up on the axis. The passthru options did occur to me when I started thinking about the color. I twisted it so it is now available for the scatter graph, for the qfit graph, and for both graphs (the twoway). The program now comes with options for saving the graph points should someone wants to make a graph on their own. An interesting extension is to make a similar graph across estimates, sort of like a graphic version of a regression table. It should be useful when CI is added. Feel free to chime in if someone has suggestions. If anyone knows how to pass the label values to the graph values (replace 1, 2, etc, with value labels on the axis), I would be interested.
