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

SSYYNNOOPPSSIISS

       use the helper to create your View myapp_create.pl view RRDGraph RRD�
       Graph

       from the controller:

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

           $c->stash->{â�TMgraphâ�TM} = [
                   "--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(â�TMMyApp::View::RRDGraphâ�TM);
         }

DDEESSCCRRIIPPTTIIOONN

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

CCOONNFFIIGGUURRAATTIIOONN

Configurations for the view are:

IIMMGG__DDIIRR

Directory to generate temporary image files. Defaults to //ttmmpp//

IIMMGG__FFOORRMMAATT

Image format for the generated files. â�^TMPNGâ�^TM by default.

OONN_EERRRROORR_SSEERRVVEE

       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). Alter�
       nately, it can be set to a code reference, that will called with $$sseellff,
       $$cc and $$eerrrroorr. You can then generate your own content in this handler.
       Default (leaving undefined) is to throw an expception.
