-wide, and separated by one pixel, and the graph is 13 pixels tall. Width is
-determined automatically for bar graphs. The points with negative values
-are colored red, instead of the default black.

-The form for the data points is "x,y" for line graphs, or just "y" if the x
-values don't matter. Bar graphs can also add "(color)" to specify a color
-for that bar.

The following named parameters are recognised. Most of these are the same
as those used by the underlying sparkline library, which is documented in
