I did my own version of it and it looks like this:
Manipulate[Block[{spl = ListLinePlot[Final, PlotRange -> {{0, 2}, {1,
6.5}}]},
Show[spl, Graphics[{Red, PointSize[.02], Point[{Final[[j, 1]],
Final[[j, 2]]}]}]]], {j, 1, 187}] (I believe the brackets are fine.)
Final is a 187=D72 Table with x,y values of the graph. The animation
itself works like it should, but a few of the frames turn a red
background and I get these warnings:
Part::pspec: Part specification 89.4` is neither an integer nor a list
of integers. >>
Am I doing something wrong?
