NAME

       CGI::Application::Plugin::DBIProfile::Graph::HTML - VERY basic pure html vertical bar graphing for CAP:DBIProfile.

SYNOPSIS

	   # in httpd.conf
	   SetVar CAP_DBIPROFILE_GRAPHMODULE CGI::Application::Plugin::DBIProfile::Graph::HTML
	   PerlSetVar CAP_DBIPROFILE_GRAPHMODULE CGI::Application::Plugin::DBIProfile::Graph::HTML

DESCRIPTION

       This module is provided as a basic implementation of graphing for CAP:DBIProfile. It can be used as an example to develop other, more
       sophisticated, graphing solutions.

GRAPH PLUGIN DEVELOPMENT

       The graphing plugin must have a method called "build_graph", which must accept options as a hash.

       It should return a scalar or scalar ref holding the HTML output needed to generate your graph.

       The following options will be passed to the "build_graph" method:

       self
	   The cgiapp object.

       mode_param
	   $self->mode_param - the runmode variable used to determine runmode (useful for creating links back to ourselves).

       title
	   A textual title for your graph. You don't have to use this, but is there if you want it.

       ylabel
	   Label for values we're graphing. Either "Count" or "Seconds".

       data
	   An array of the datapoints to graph.

       tags
	   Labels for each datapoint which match the labels that will be used on the sql statement list (1 to however many items there are).

       The easiest graphs to implement are fully inline - ie. it doesn't need to make any external calls (no <image> or <embed> tags and such).
       CGI::Application::Plugin::DBIProfile::Graph::HTML is an example of this. Other possible candidates are Plotr and Open Flash Chart (using js
       interface to populate data).

       Another inline solution is to use the <img src="data:uri"> scheme. An example of this can be found in
       CGI::Application::Plugin::DBIProfile::Graph::GDGraphInline. Please note, this isn't supported under MSIE.

       In order to generate a graph that isn't inline, you'll need to pass the data to be graphed with your call to the external object. For
       example, if you want to use GDGraph, you could create a separate cgi script that returns graphs based on params passed to it, and return an
       approapriate image tag to from your graphing module. For example:

	   <img src="/cgi-bin/graph.pl?data=20,14,42&tags=1,2,3">

       Another way, would be to add a runmode in a CGI::Application "init" hook, and pass that runmode in a link back to the same script, and
       include your graph module in our script with a use statement. An example of this can be found in
       CGI::Application::Plugin::DBIProfile::Graph::SVGTT.

NAME

       CGI::Application::Plugin::DevPopup::Timing - show timing information about cgiapp stages

VERSION

       version 1.07

SYNOPSIS

	   use CGI::Application::Plugin::DevPopup;
	   use CGI::Application::Plugin::DevPopup::Timing;

	   The rest of your application follows
	   ...

       Output will look roughly like this:

	   Timings
	   Total runtime: 3.1178 sec.
	   Application started at: Thu Sep 22 02:55:35 2005

	   From 		       To			       Time taken
	   -------------------------------------------------------------------------
	   init 		       prerun			       0.107513 sec.
	   prerun		       before expensive operation      0.000371 sec.
	   before expensive operation  after expensive operation       3.006688 sec.
	   after expensive operation   load_tmpl(dp.html)	       0.000379 sec.
	   load_tmpl(dp.html)	       postrun			       0.002849 sec.

ADD_TIMING
       You can add your own timing points within your application by calling the hook at "devpopup_addtiming" with a short label. The table above
       was created with the following code:

	   $self->call_hook('devpopup_addtiming', 'before expensive operation');
	   sleep 3;
	   $self->call_hook('devpopup_addtiming', 'after expensive operation');
