NAME

       Jifty::Plugin::Chart::Renderer - Base class for chart rendering classes

SYNOPSIS

       In your config.yml:

	 Plugins:
	   - Chart:
	       DefaultRenderer: MyApp::Renderer

       In lib/MyApp/Renderer.pm:

	 package MyApp::Renderer;
	 use base qw/ Jifty::Plugin::Chart::Renderer /;

	 sub init {
	     my $self = shift;

	     # Handle any required initialization, like required CSS, JS, etc.
	 }

	 sub render {
	     my $self = shift;
	     my %args = @_;

	     # Output your chart
	     Jifty->web->out( #{ Output your chart here... } );

	     # You could also return it as a string...
	     return;
	 }

METHODS

       Your renderer implementation must subclass this package and implement the following methods:

   new
       This is the constructor. Don't override this directly. Instead implement "init".

   init
	 $renderer->init();

       This is called by "new" immediately after constructing the object.  It is passed a param hash from the config file.  Subclasses should
       implement this method to do any required initialization such as letting Jifty know about required CSS files, JS files, etc.

   render
	 Jifty->web->out($renderer->render(%args));

       See Jifty::Plugin::Chart::Web for the arguments. It must (at least) accept the arguments given to the "chart" in Jifty::Plugin::Chart::Web
       method.

       The "render" method may either return it's output or print it out using Jifty::Web::out.
