Generates graph profile reports as html. To use the graph html printer:
result = RubyProf.profile do [code to profile] end printer = RubyProf::GraphHtmlPrinter.new(result) printer.print(STDOUT, :min_percent=>0)
The Graph printer takes the following options in its print methods:
:filename - specify a file to use that contains the ERB
template to use, instead of the built-in self.template
:template - specify an ERB template to use, instead of the
built-in self.template
Creates a link to a method. Note that we do not create links to methods which are under the min_perecent specified by the user, since they will not be printed out.
