I'm using Excel 2007.  I have a simple column chart that counts
widgets by year.  There are 10 different sorts of widgets.  My
question is, is there a way where I can easily select which widgets I
want to display on the chart?  In other words, if My legend looked
like this..

Widget A
Widget B
Widget C
Widget D
Widget E
etc....

I would like the ability to select say, Widget A and Widget C and have
the graph automatically update.  Does anyone know if this is possible
in Excel 2007?

Thanks!
Mike
