NAME

OpenGuides::Statistics - generate graphs of the number of nodes on an OpenGuides site

SYNOPSIS

use OpenGuides::Statistics;

my $stats = 
  OpenGuides::Statistics->new( wiki_conf   => '/path/to/your/openguides/wiki.conf',
                               import_date => '2000-01-01' );
  
my ($total_graph, $rate_graph) = $stats->make_graphs;
my $node_count                 = $stats->node_count;

DESCRIPTION

This module will read your OpenGuides database and produce Chart::Strip graphs of the data therein to show you how fast you've accumulated nodes.

METHODS

new()

my $stats =
  OpenGuides::Statistics->new( wiki_conf   => '/path/to/your/openguides/wiki.conf',
                               import_date => '2000-01-01' );

There's only one required argument, wiki_conf. This is a path to the configuration file of your OpenGuides installation, which this module will load to know how to access your wiki's database. Optional arguments:

  • import_date Use this to ignore a certain date when reading the node creation dates from your database. This is useful if your database was created by importing an existing database, which would otherwise cause a large spike at the beginning of your graph. Takes a date string in the format yyyy-mm-dd.

  • graph_width Width in pixels of your graphs. Defaults to 640.

  • graph_height Height in pixels of your graphs. Defaults to 480.

  • total_colour The colour of the filled area in the "total nodes" graph. Must be a six-digit hex colour, e.g. 6699CC. Defaults to 000000.

  • rate_line_colour The colour of the line in the rate graph. Defaults to 000000.

  • rate_points_colour The colour of the points in the rate graph. Defaults to 000000.

make_graphs()

my ($total_graph, $rate_graph) = $stats->make_graphs;

This method will return two Chart::Strip objects, which have three possible output methods: png() (returns a PNG image), jpeg() (returns a JPEG image) and gd() (returns an underlying GD object). An example of how to use the objects is included in the 'examples' directory of this distribution.

node_count()

my $node_count = $stats->node_count;

This method will return a scalar value of how many nodes there are in your database.
