NAME
   Chart::OFC2 - Generate html and data files for use with Open Flash Chart
   version 2

SYNOPSIS
   OFC2 html:

       use Chart::OFC2;

       my $chart = Chart::OFC2->new(
           'title'  => 'Bar chart test',
       );
       print $chart->render_swf(600, 400, 'chart-data.json', 'test-chart');

   OFC2 bar chart data:

       use Chart::OFC2;
       use Chart::OFC2::Axis;
       use Chart::OFC2::Bar;

       my $chart = Chart::OFC2->new(
           'title'  => 'Bar chart test',
           x_axis => {
               labels => {
                   labels => [ 'Jan', 'Feb', 'Mar', 'Apr', 'May' ],
               }
           },
       );

       my $bar = Chart::OFC2::Bar->new();
       $bar->values([ 1..5 ]);
       $chart->add_element($bar);

       print $chart->render_chart_data();

WARNING
   Current version implements just subset of functionality that Open Flash
   Chart 2 is offering. But it should help you to starting creating OFC2
   graphs quite fast. The JSON format is quite intuitive and can be created
   from any hash. This module is more like guideline.

   This is early version PROTOTYPE so the API WILL change, be careful when
   upgrading versions.

DESCRIPTION
   OFC2 is a flash script for creating graphs. To have a graph we need an
   open-flash-chart.swf and a JSON data file describing graph data.
   Complete examples you can find after successful run of this module tests
   in t/output/ folder - t/output/bar.html, t/output/pie.html,
   t/output/hbar.html are html graphs and t/output/bad-data.json,
   t/output/pie-data.json, t/output/hbar-data.json are the data files.

PROPERTIES
       has 'data_load_type' => (is => 'rw', isa => 'Str',  default => 'inline_js');
       has 'bootstrap'      => (is => 'rw', isa => 'Bool', default => '1');
       has 'title'          => (is => 'rw', isa => 'Chart::OFC2::Title', default => sub { Chart::OFC2::Title->new() }, lazy => 1, coerce  => 1);
       has 'x_axis'         => (is => 'rw', isa => 'Chart::OFC2::XAxis', default => sub { Chart::OFC2::XAxis->new() }, lazy => 1,);
       has 'y_axis'         => (is => 'rw', isa => 'Chart::OFC2::YAxis', default => sub { Chart::OFC2::YAxis->new() }, lazy => 1, );
       has 'elements'       => (is => 'rw', isa => 'ArrayRef', default => sub{[]}, lazy => 1);
       has 'extremes'       => (is => 'rw', isa => 'Chart::OFC2::Extremes',  default => sub { Chart::OFC2::Extremes->new() }, lazy => 1);
       has 'tooltip'        => (is => 'rw', isa => 'Chart::OFC2::ToolTip',);
       has 'bg_colour'      => (is => 'rw', isa => 'Str',  default => 'f8f8d8', alias => 'bg_color' );

METHODS
 new()
   Object constructor.

 get_element($type)
   Returns new chart object of selected type. Currently only `bar' and
   `pie' is available.

 add_element($element)
   Adds passed element to the graph.

 render_chart_data
   Returns stringified JSON encoded graph data.

 auto_extremes
   Recalculate graph auto extremes.

 render_swf($width, $height, $data_url, $div_id)
   Returns html snippet that will represent one graph in a html document.

   WARN: the arguments format will change to `key =' value> in the next
   releases.

FUNCTIONS
 smoother_number
   round the number up a bit to a nice round number also changes number to
   an int

 smooth($axis_name, $axis_type)
   Smooth axis min/max.

 bg_color()
   Same as bg_colour().

NOTE
   Refresh button will not cause the data file of the graph to be reloaded
   so either use proper expiration settings for it or change the name of
   the file in html every time you generate new data. Like
   `"data.json?".time()'.
