This makes a simple plot of each series in a tree-ring data set. Each
series is centered first by subtracting the column mean using
scale
. The plot can be grossly tuned with
zfac
which is a multiplier to rwl
before
plotting and centering.
None. This function is invoked for its side effect, which is to produce a plot.
