Graphing library?


#1

Hello everyone,

I’m looking to produce some graphs broadly like the ones shown here:
http://www.dotnetcharting.com/gallery/List.aspx?gal=6 No prize for
guessing what type of app it is…

This particular graphing library is .NET-specific, but as you can see
the results it produces are really nice. More than likely, they’re
several notches above what I’ll be able to produce if I start with
something low level (such as GD) under Rails/Ruby.

Is there a Ruby graphing library that produces output broadly along
the lines of this library, without having to invest huge amounts of
effort massaging the output?

Thanks in advance

Dave M.
