Re: st: gra command

[Nick Cox <njcoxstata@gmail.com>]

Indeed, but I also explained that it uses version control, so it still
works. The only thing out-of-date  about -cusum6-  is that its graphs
cannot be edited in versions of Stata from 8 on.

What is out-of-date is the graphics advice in the document you
downloaded from Royal Holloway, London and I gave some advice on how
to plot results from this method.

As I said, I am working on time series data and want to label my X axis so I could identify (with th cusum6 command) break point; but, I can't edit myself. I would like to know if there is a command telling stata to put all my time-periods (quarter) on the X axis.

To say it frankly, it's my first time using stata and I have stata12; therefore it's hard for me to know what has changed and from where. How about the other problems I long for answers?
