MongoDB入门教程
rake stats可以生成统计代码行数，类的个数，方法的个数等信息，今天我们看看怎样生成rake stats的饼状图。
1，安装ImageMagick
什么新立得包管理器装一下或者apt-get装一下或者下载binary包安装
2，安装RMagick
3，安装Gruff
4，写生成饼状stats图的controller
访问GraphController的stats方法即可。
但是页面会报错:
不管是Windows还是Linux下均报这个错，不知道怎么回事。

class GraphController < ApplicationController
require 'gruff'

%w(Functional\ tests test/functional),

}.select { |name, dir|
File.directory?(dir)
}
def stats
code_stats = CodeStatistics.new(*STATS_DIRECTORIES)
statistics = code_stats.instance_variable_get(:@statistics)
g = Gruff::Pie.new(500)
g.font = "/Library/Fonts/Arial"
g.title = "Code Stats"
g.theme_37signals
g.legend_font_size = 10
0xFDD84E.step(0xFF0000, 1500) do |num|
g.colors << "#%x" % num
end
statistics.each do |key, values|
g.data(key, [values["codelines"]])
end
send_data(g.to_blob,
:disposition => ' inline' ,
:type => ' image/png' ,

end
end
