NAME

       Column - A class for writing Excel Column charts.

SYNOPSIS

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

           #!/usr/bin/perl

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

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

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

           # Configure the chart.
           $chart->add_series(
               categories => '=Sheet1!$A$2:$A$7',
               values     => '=Sheet1!$B$2:$B$7',
           );

           # Add the worksheet data the chart refers to.
           my $data = [
               [ 'Category', 2, 3, 4, 5, 6, 7 ],
               [ 'Value',    1, 4, 5, 2, 1, 5 ],
           ];

           $worksheet->write( 'A1', $data );

           __END__

DESCRIPTION

       This module implements Column charts for Excel::Writer::XLSX. The chart object is created
       via the Workbook "add_chart()" method:

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

       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.

Column Chart Subtypes

       The "Column" chart module also supports the following sub-types:

           stacked
           percent_stacked

       These can be specified at creation time via the "add_chart()" Worksheet method:

           my $chart = $workbook->add_chart( type => 'column', subtype => 'stacked' );

EXAMPLE

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

           #!/usr/bin/perl

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

           my $workbook  = Excel::Writer::XLSX->new( 'chart_column.xlsx' );
           my $worksheet = $workbook->add_worksheet();
           my $bold      = $workbook->add_format( bold => 1 );

           # Add the worksheet data that the charts will refer to.
           my $headings = [ 'Number', 'Batch 1', 'Batch 2' ];
           my $data = [
               [ 2, 3, 4, 5, 6, 7 ],
               [ 10, 40, 50, 20, 10, 50 ],
               [ 30, 60, 70, 50, 40, 30 ],

           ];

           $worksheet->write( 'A1', $headings, $bold );
           $worksheet->write( 'A2', $data );

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

           # Configure the first series.
           $chart->add_series(
               name       => '=Sheet1!$B$1',
               categories => '=Sheet1!$A$2:$A$7',
               values     => '=Sheet1!$B$2:$B$7',
           );

           # Configure second series. Note alternative use of array ref to define
           # ranges: [ $sheetname, $row_start, $row_end, $col_start, $col_end ].
           $chart->add_series(
               name       => '=Sheet1!$C$1',
               categories => [ 'Sheet1', 1, 6, 0, 0 ],
               values     => [ 'Sheet1', 1, 6, 2, 2 ],
           );

           # Add a chart title and some axis labels.
           $chart->set_title ( name => 'Results of sample analysis' );
           $chart->set_x_axis( name => 'Test number' );
           $chart->set_y_axis( name => 'Sample length (mm)' );

           # Set an Excel chart style. Blue colors with white outline and shadow.
           $chart->set_style( 11 );

           # Insert the chart into the worksheet (with an offset).
           $worksheet->insert_chart( 'D2', $chart, 25, 10 );

           __END__
