=head1 NAME

SVG::TT::Graph::BarHorizontal - Create presentation quality SVG horizontal bar graphs easily

=head1 SYNOPSIS

  use SVG::TT::Graph::BarHorizontal;

  my @fields = qw(Jan Feb Mar);
  my @data_sales_02 = qw(12 45 21);
  
  my $graph = SVG::TT::Graph::BarHorizontal->new({
    'height' => '500',
    'width' => '300',
    'fields' => \@fields,
  });
  
  $graph->add_data({
    'data' => \@data_sales_02,
    'title' => 'Sales 2002',
  });
  
  print "Content-type: image/svg+xml\n\n";
  print $graph->burn();

=head1 DESCRIPTION

This object aims to allow you to easily create high quality
SVG horitonzal bar graphs. You can either use the default style sheet
or supply your own. Either way there are many options which can
be configured to give you control over how the graph is
generated - with or without a key, data elements at each point,
title, subtitle etc.

=head1 METHODS

=head2 new()

  use SVG::TT::Graph::BarHorizontal;
  
  # Field names along the X axis
  my @fields = qw(Jan Feb Mar);
  
  my $graph = SVG::TT::Graph::BarHorizontal->new({
    # Required
    'fields'                 => \@fields,
  
    # Optional - defaults shown
    'height'                 => '500',
    'width'                  => '300',

    'show_data_values'       => 1,

    'scale_divisions'        => '',
    'min_scale_value'        => '0',
    'bar_gap'                => 1,

    'show_x_labels'          => 1,
    'stagger_x_labels'       => 0,
    'show_y_labels'          => 1,
    'scale_integers'         => 0,

    'show_x_title'           => 0,
    'x_title'                => 'X Field names',

    'show_y_title'           => 0,
    'y_title_text_direction' => 'bt',
    'y_title'                => 'Y Scale',

    'show_graph_title'       => 0,
    'graph_title'            => 'Graph Title',
    'show_graph_subtitle'    => 0,
    'graph_subtitle'         => 'Graph Sub Title',
    'key'                    => 0,
    'key_position'           => 'right',

    # Stylesheet defaults
    'style_sheet'             => '/includes/graph.css', # internal stylesheet
    'random_colors'           => 0,
  });

The constructor takes a hash reference, only fields (the names for each
field on the X axis) MUST be set, all other values are defaulted to those
shown above - with the exception of style_sheet which defaults
to using the internal style sheet.

=head2 add_data()

  my @data_sales_02 = qw(12 45 21);

  $graph->add_data({
    'data'  => \@data_sales_02,
    'title' => 'Sales 2002',
  });

This method allows you to add data to the graph object.
It can be called several times to add more data sets in,
but the likelihood is you should be using SVG::TT::Graph::Line
as it won't look great!

=head2 clear_data()

  my $graph->clear_data();

This method removes all data from the object so that you can
reuse it to create a new graph but with the same config options.

=head2 burn()

  print $graph->burn();

This method processes the template with the data and
config which has been set and returns the resulting SVG.

This method will croak unless at least one data set has
been added to the graph object.

=head2 config methods

  my $value = $graph->method();
  my $confirmed_new_value = $graph->method($value);
  
The following is a list of the methods which are available
to change the config of the graph object after it has been
created.

=over 4

=item height()

Set the height of the graph box, this is the total height
of the SVG box created - not the graph it self which auto
scales to fix the space.

=item width()

Set the width of the graph box, this is the total width
of the SVG box created - not the graph it self which auto
scales to fix the space.

=item compress()

Whether or not to compress the content of the SVG file (Compress::Zlib required).

=item tidy()

Whether or not to tidy the content of the SVG file (XML::Tidy required).

=item style_sheet()

Set the path to an external stylesheet, set to '' if
you want to revert back to using the defaut internal version.

The default stylesheet handles up to 12 data sets. All data series over
the 12th will have no style and be in black. If you have over 12 data
sets you can assign them all random colors (see the random_color()
method) or create your own stylesheet and add the additional settings
for the extra data sets.

To create an external stylesheet create a graph using the
default internal version and copy the stylesheet section to
an external file and edit from there.

=item random_colors()

Use random colors in the internal stylesheet

=item show_data_values()

Show the value of each element of data on the graph

=item bar_gap()

Whether to have a gap between the bars or not, default
is '1', set to '0' if you don't want gaps.

=item min_scale_value()

The point at which the Y axis starts, defaults to '0',
if set to '' it will default to the minimum data value.

=item show_x_labels()

Whether to show labels on the X axis or not, defaults
to 1, set to '0' if you want to turn them off.

=item stagger_x_labels()

This puts the labels at alternative levels so if they
are long field names they will not overlap so easily.
Default it '0', to turn on set to '1'.

=item show_y_labels()

Whether to show labels on the Y axis or not, defaults
to 1, set to '0' if you want to turn them off.

=item scale_integers()

Ensures only whole numbers are used as the scale divisions.
Default it '0', to turn on set to '1'. This has no effect if 
scale divisions are less than 1.

=item scale_divisions()

This defines the gap between markers on the X axis,
default is a 10th of the max_value, e.g. you will have
10 markers on the X axis. NOTE: do not set this too
low - you are limited to 999 markers, after that the
graph won't generate.

=item show_x_title()

Whether to show the title under the X axis labels,
default is 0, set to '1' to show.

=item x_title()

What the title under X axis should be, e.g. 'Months'.

=item show_y_title()

Whether to show the title under the Y axis labels,
default is 0, set to '1' to show.

=item y_title_text_direction()

Aligns writing mode for Y axis label. Defaults to 'bt' (Bottom to Top).
Change to 'tb' (Top to Bottom) to reverse.

=item y_title()

What the title under Y axis should be, e.g. 'Sales in thousands'.

=item show_graph_title()

Whether to show a title on the graph,
default is 0, set to '1' to show.

=item graph_title()

What the title on the graph should be.

=item show_graph_subtitle()

Whether to show a subtitle on the graph,
default is 0, set to '1' to show.

=item graph_subtitle()

What the subtitle on the graph should be.

=item key()

Whether to show a key, defaults to 0, set to
'1' if you want to show it.

=item key_position()

Where the key should be positioned, defaults to
'right', set to 'bottom' if you want to move it.
