Jifty::Plugin::Chart::Renderer.3pm

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.
