We had the same problem recently. Derek Wagner of StataCorp sent me this: ----------------------------- After testing the problem, it appears that -graph matrix- doesn't like a single upper-case letter as a variable label. I have forwarded the issue on to Vince, so hopefully there will be a change in the next update. In the meantime, you could graph your results by either getting rid of the variable labels (especially B, K, V, etc.) or change them to lower-case. --------------------------- This seems consistent with what you did, as your copies produced by -generate- are born without variable labels.
