Gruff
Tonight I wanted to do something with Ruby Sparklines but I couldn’t get it to install so I somehow ended up playing with Gruff instead. You will now be impressed as I show a graph of words and comments in each of the posts for this weblog:
Well, perhaps not. I was though.
#!/usr/bin/ruby
require 'rubygems'
require 'gruff/base'
g = Gruff::Line.new(360)
g.title = "I'm just playing with gruff"
# this is only a subset of the above image
g.data("Comments", [0, 0, 0, 0 ]
# again, this is only a subset of the above image
g.data("Words", [257, 125, 87, 46 ]
g.write('comments.png')
I had to require grruff/base as require gruff wasn’t happening. Works though. Perhaps someone can tell me why require gruff didn’t work? I’m guessing RMagick or ImageMagick…

Does exactly what it says on the (comic book) tin. Loved it. - Little Miss Sunshine

Very funny, disturbing (the beauty pageant) and completely messed up -- but in a good way. - Laputa: Castle in the Sky†
Story great, characterization a little on the weak side -- though the big robots are cool. - Porco Rosso

Stylish, funny, exciting. - Grave of the Fireflies†
Very sad, which was a little unexpected since I didn't know much about it before watching it. Can be a little too slow in places though, otherwise it's very good. - Nausicaä of the Valley of the Wind†
The story can get a little dense at times what with the various factions, but still really enjoyable, inventive and engaging. - X-Men: The Last Stand

Opportunity, talent, money - all blown. Over 3 films X-Men has hinted of something great that could have been, this last one says "No, sorry - not going to happen". Bah.
