Friedrich Huebler ([email protected]) experienced problems
exporting a graph containing a very large amount of data to
emf or wmf format (you can read his full email after my
signature below).
After experimenting here and reproducing Friedrich's problem,
I sent him a test executable which may solve the issues he was
experiencing. After he has had a chance to confirm that, we'll
report back to Statalist on the issue.
