= Description
Produces a graph of temporal scalar data.
= Examples
http://www.germane-software/repositories/public/SVG/test/timeseries.rb
= Notes
The default stylesheet handles upto 10 data sets, if you
use more you must create your own stylesheet and add the
additional settings for the extra data sets. You will know
if you go over 10 data sets as they will have no style and
be in black.
Unlike the other types of charts, data sets must contain x,y pairs:
["12:30", 2] # A data set with 1 point: ("12:30",2)
["01:00",2, "14:20",6] # A data set with 2 points: ("01:00",2) and
# ("14:20",6)
Note that multiple data sets within
the same chart can differ in length,
and that the data in the datasets needn't be in order;
they will be ordered by the plot along the X-axis.
The dates must be parseable by ParseDate, but otherwise can be
any order of magnitude (seconds within the hour, or years)
