NAME

       Stock - A class for writing Excel Stock charts.

SYNOPSIS

       To create a simple Excel file with a Stock chart using Excel::Writer::XLSX:

           #!/usr/bin/perl -w

           use strict;
           use Excel::Writer::XLSX;

           my $workbook  = Excel::Writer::XLSX->new( 'chart.xlsx' );
           my $worksheet = $workbook->add_worksheet();

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

           # Add a series for each 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'
           );

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

           __END__

DESCRIPTION

       This module implements Stock charts for Excel::Writer::XLSX. 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 Excel::Writer::XLSX::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
       Excel::Writer::XLSX::Chart.

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

EXAMPLE

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

           #!/usr/bin/perl

           use strict;
           use warnings;
           use Excel::Writer::XLSX;
           use Excel::Writer::XLSX;

           my $workbook    = Excel::Writer::XLSX->new( 'chart_stock.xlsx' );
           my $worksheet   = $workbook->add_worksheet();
           my $bold        = $workbook->add_format( bold => 1 );
           my $date_format = $workbook->add_format( num_format => 'dd/mm/yyyy' );
           my $chart       = $workbook->add_chart( type => 'stock', embedded => 1 );

           # Add the worksheet data that the charts will refer to.
           my $headings = [ 'Date', 'High', 'Low', 'Close' ];
           my $data = [

               [ '2007-01-01T', '2007-01-02T', '2007-01-03T', '2007-01-04T', '2007-01-05T' ],
               [ 27.2,  25.03, 19.05, 20.34, 18.5 ],
               [ 23.49, 19.55, 15.12, 17.84, 16.34 ],
               [ 25.45, 23.05, 17.32, 20.45, 17.34 ],

           ];

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

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

           }

           $worksheet->set_column( 'A:D', 11 );

           # Add a series for each of the High-Low-Close columns.
           $chart->add_series(
               categories => '=Sheet1!$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',
           );

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

           $worksheet->insert_chart( 'E9', $chart );
