My understanding is that the option *FrameRate* interprets its value
(15 by default) as /frames per second/. So if you set it to one, that
would say that you want only one image/frame per second. In your case
you want to see 60 different curves, like a slide show    if I have
correctly understood. Therefore, I guess it would be appropriate to
ask for only one or two frames per second (in doing so you reduce
enormously the size of the SWF file) but you must extend the duration
of the clip to, say, two minutes, i.e. "AnimationDuration"->120

The number of frames per second has nothing to do with the number of
"images" (or slides or pictures) you want ot include in your
presentation. The number of frames per second control the smoothness
of the movie (24 frames per second for a movie picture and 25 frame
per second for "images" broadcast on TV, if my memory is still working

The option "FlashPlayback" allows to control the setting (and display)
of interactive playback controls in the SWF file.
