Lovely charts Geert.  Two of the features I added in the Net Worth line
chart are obsoleted/broken.  Optional grid and optional data markers no
longer work as advertised so I'll have to look at them or remove
them.  Not really sure if either are necessary anyway. 

All the charts could possibly use an alternate black and white
stylesheet for printing, is this easier to achieve using jqplot?  This
is not new because of jqplot though.
