What you are looking for is the attribute VisibleFromTo which defines
the time range of visibility of objects. See chapter '10.6. Frame by
Frame Animations' of the introduction of the plot document for details.

r := random(1..99):
// I sort the random points to keep my animation smooth
// I think your input data aready is smooth
xpos := sort([r() $ i=1..99]);
ypos := sort([r() $ i=1..99]);

plot(plot::Point2d([xpos[a], ypos[a]],
VisibleFromTo=a/4..(a+1)/4) $ a = 1..99)

The above animation cycles through your point data in 25 seconds.
