NAME
       Stock - A writer class for Excel Stock charts.

SYNOPSIS
       To create a simple Excel file with a Stock chart using Spreadsheet::WriteExcel:

           #!/usr/bin/perl -w

           use strict;
           use Spreadsheet::WriteExcel;

           my $workbook  = Spreadsheet::WriteExcel->new( 'chart.xls' );
           my $worksheet = $workbook->add_worksheet();

           my $chart     = $workbook->add_chart( type => 'stock' );

           # Add a series for each Open-High-Low-Close.
           $chart->add_series( categories => '=Sheet1!$A$2:$A$6', values => '=Sheet1!$B$2:$B$6' );
           $chart->add_series( categories => '=Sheet1!$A$2:$A$6', values => '=Sheet1!$C$2:$C$6' );
           $chart->add_series( categories => '=Sheet1!$A$2:$A$6', values => '=Sheet1!$D$2:$D$6' );
           $chart->add_series( categories => '=Sheet1!$A$2:$A$6', values => '=Sheet1!$E$2:$E$6' );

           # Add the worksheet data the chart refers to.
           # ... See the full example below.

           __END__

DESCRIPTION
       This module implements Stock charts for Spreadsheet::WriteExcel. The chart object is
       created via the Workbook "add_chart()" method:

           my $chart = $workbook->add_chart( type => 'stock' );

       Once the object is created it can be configured via the following methods that are common
       to all chart classes:

           $chart->add_series();
           $chart->set_x_axis();
           $chart->set_y_axis();
           $chart->set_title();

       These methods are explained in detail in Spreadsheet::WriteExcel::Chart. Class specific
       methods or settings, if any, are explained below.

Stock Chart Methods
       There aren't currently any stock chart specific methods. See the TODO section of
       Spreadsheet::WriteExcel::Chart.

       The default Stock chart is an Open-High-Low-Close chart. A series must be added for each
       of these data sources.

       The default Stock chart is in black and white. User defined colours will be added at a
       later stage.

EXAMPLE
       Here is a complete example that demonstrates most of the available features when creating
       a Stock chart.

           #!/usr/bin/perl -w

           use strict;
           use Spreadsheet::WriteExcel;

           my $workbook    = Spreadsheet::WriteExcel->new( 'chart_stock_ex.xls' );
           my $worksheet   = $workbook->add_worksheet();
           my $bold        = $workbook->add_format( bold => 1 );
           my $date_format = $workbook->add_format( num_format => 'dd/mm/yyyy' );

           # Add the worksheet data that the charts will refer to.
           my $headings = [ 'Date', 'Open', 'High', 'Low', 'Close' ];
           my @data = (
               [ '2009-08-23', 110.75, 113.48, 109.05, 109.40 ],
               [ '2009-08-24', 111.24, 111.60, 103.57, 104.87 ],
               [ '2009-08-25', 104.96, 108.00, 103.88, 106.00 ],
               [ '2009-08-26', 104.95, 107.95, 104.66, 107.91 ],
               [ '2009-08-27', 108.10, 108.62, 105.69, 106.15 ],
           );

           $worksheet->write( 'A1', $headings, $bold );

           my $row = 1;
           for my $data ( @data ) {
               $worksheet->write( $row, 0, $data->[0], $date_format );
               $worksheet->write( $row, 1, $data->[1] );
               $worksheet->write( $row, 2, $data->[2] );
               $worksheet->write( $row, 3, $data->[3] );
               $worksheet->write( $row, 4, $data->[4] );
               $row++;
           }

           # Create a new chart object. In this case an embedded chart.
           my $chart = $workbook->add_chart( type => 'stock', embedded => 1 );

           # Add a series for each of the Open-High-Low-Close columns.
           $chart->add_series(
               categories => '=Sheet1!$A$2:$A$6',
               values     => '=Sheet1!$B$2:$B$6',
               name       => 'Open',
           );

           $chart->add_series(
               categories => '=Sheet1!$A$2:$A$6',
               values     => '=Sheet1!$C$2:$C$6',
               name       => 'High',
           );

           $chart->add_series(
               categories => '=Sheet1!$A$2:$A$6',
               values     => '=Sheet1!$D$2:$D$6',
               name       => 'Low',
           );

           $chart->add_series(
               categories => '=Sheet1!$A$2:$A$6',
               values     => '=Sheet1!$E$2:$E$6',
               name       => 'Close',
           );

           # Add a chart title and some axis labels.
           $chart->set_title( name => 'Open-High-Low-Close', );
           $chart->set_x_axis( name => 'Date', );
           $chart->set_y_axis( name => 'Share price', );

           # Insert the chart into the worksheet (with an offset).
           $worksheet->insert_chart( 'F2', $chart, 25, 10 );
