Hi Graham, If I understand well your message, your plots have a lot of data points and since each point is represented as a vector object, the vector based formats like eps or pdf become huge. For such graphics, I generally choose to flatten them using a bitmap format (jpg or png) with a sufficient density (like 300 dpi). This gives relatively small size (in comparison with the vector format, and acceptable print quality). These bitmap formats are normally compatible with pdflatex. Otherwise, you can always convert them to eps (but they will be just bitmaps enclosed in an vector enveloppe) for using with a dvips based chain.
I hope this can help you.
