I have had a very hard time trying to get the gruff graphs gem working.
i have the rails recipes book and wasn't intimidated when it said it
could get kinda hairy installing gruff and more specifically the evil
prerequisites ImageMagick and RMagick.
i read http://rmagick.rubyforge.org/install-faq.html and tried
installing from source code. i think that evil clown has cursed me.
was so annoyed by my experience trying to set this up that i looked at
some alternatives.. all i found was scruffy and sparklines.. scruffy
doesn't do pie charts which is what i think would work the best for the
reports i specifically have in mind. sparklines does little itty bitty
icon graphs.. not exactly what i'm looking for but the page shows
examples of the tiny graphs being scaled up. anyway, also tried getting
that working.. no dice. maybe i'm just an idiot, but i didn't have any
problem getting other gems and plugins working.
any help would greatly be appreciated.
