Re: st: large eps files created from stata graphs [SEC=UNCLASSIFIED]

[Jennifer Baxter <Jennifer.Baxter@aifs.gov.au>]

I have resolved this problem. The EPS file size was very large because this graph was generated using the unit record data (several thousand 
records), even though I was only needing to graph aggregate data.  I dropped all but the information I need for the graph and have now got a much more manageable size. Jenny

It seems that adding confidence intervals doubles the original size, then adding labels doubles this again.  I have been asked to provide EPS files otherwise I would export to a different format.
