I'm asking a general question about whether excess data gets stored in a
graphic when the data that's supplied to create the graphic has a lot
more data than is needed to create the graphic. In particular:
1) If you make a ListPlot of a large array in which the majority of the
array points fall way outside the boundaries of the explicitly given
PlotRange, is all the "unused" data from the array still somehow stored
in the graphic, either internally or when it's Exported as an EPS file?
2) Same question, except assuming you make a ListPlot of an array using
PlotJoined->True where the array has say 1000 point pairs, but only
about 6 points are needed to define the simple curve that shows up in
the graphic. Are the 1000 points carried into the Exported EPS graphic,
or only a much smaller number?
