Figure 2 zooms in on growth by using measurements of a boy's height
at 83 days over one school year, with gaps corresponding to the
school vacations. The measurement noise in the data, of standard
deviation about 3 mm, is apparent. The trend is also noticeably
more bumpy, with height increasing more rapidly over some weeks
than others.

The solid curve is a smooth monotone fit to the data, as described in
the example Monotone Smoothing of the Growth Data.
