NAME
   Catalyst::View::RRDGraph - RRD Graph View Class

SYNOPSIS
   use the helper to create your View myapp_create.pl view RRDGraph
   RRDGraph

   from the controller:

     sub routine :Local {
       my ($self, $c) = @_;

       $c->stash->{'graph'} = [
               "--lower-limit", "0",
               "--start", "end-1d",
               "--vertical-label", "My Label",
               "--height", 600,
               "--width", 300,
               "DEF:Data=/path/to/rrd.rrd:data:AVERAGE",
               "AREA:Data#0000FF:Data "
       ];
       $c->forward('MyApp::View::RRDGraph');
     }

DESCRIPTION
   This view generates RRD graph images from the graph defintion placed in
   the stash. The controller is responsable of placing an ARRAYREF in
   $c-stash->{'graph'}> with the same data as to generate a graph with the
   RRDs module, except for *filename*, that will be automatically generated
   by the view.

   It doesn't depend on RRDs, but *does* need it to work (and for the tests
   to pass). You can install RRDs, for instance, using Alien::RRDtool, or
   compiling it manually from <http://oss.oetiker.ch/rrdtool/>

CONFIGURATION
   Configurations for the view are:

 IMG_DIR
   Directory to generate temporary image files. Defaults to /tmp/

 IMG_FORMAT
   Image format for the generated files. 'PNG' by default.

 ON_ERROR_SERVE
   On error, if this config value is set, the file to which it points will
   be served (so you can serve an "error image" file to the user).
   Alternately, it can be set to a code reference, that will called with
   $self, $c and $error. You can then generate your own content in this
   handler. Default (leaving undefined) is to throw an expception.

   See <http://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html> for more info.

METHODS
 new
   Constructor.

 process
   Called internally by Catalyst when the view is used.
