In a time series observations are
recorded in sequential order. They are plotted with time
measured on the horizontal axis and the observations
measured on the vertical axis. Line
segments connect the plotted points. For example, the
matrix, below, shows the price of
a hypothetical stock measured weekly. The prices are read
from left to right, going down the
rows. If you don't like the recent performance, simply highlight
the last row and type + 10.
