Hi Nick,
You said "cusum6 is an old program" that's why I ask if there is a new one. 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.

Thanks

PS: I am using stata 12 with update from March20th, 2013.
