Catalyst::View::RRDGrapUhs(e3r)Contributed Perl DocumentCaattiaolnyst::View::RRDGraph(3) NNAAMMEE 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->{’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’); } DDEESSCCRRIIPPTTIIOONN This view generates RRD graph images from the graph defintion placed in the stash. The controller is responsable of placing an ARRAYREF in $$cc--stash->{’graph’}> with the same data as to generate a graph with the RRDs module, except for _f_i_l_e_n_a_m_e, that will be automatically generated by the view. CCOONNFFIIGGUURRAATTIIOONN Configurations for the view are: IIMMGG__DDIIRR Directory to generate temporary image files. Defaults to //ttmmpp// IIMMGG__FFOORRMMAATT Image format for the generated files. ’PNG’ by default. OONN__EERRRROORR__SSEERRVVEE On error, if this config value is set, the file to which it points will be served (so you can serve an "error image" file to the user). Alter‐ nately, it can be set to a code reference, that will called with $$sseellff, $$cc and $$eerrrroorr. You can then generate your own content in this handler. Default (leaving undefined) is to throw an expception. See http://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html for more info. MMEETTHHOODDSS nneeww Constructor. pprroocceessss Called internally by Catalyst when the view is used.
