Spreadsheet::WriteExcel::Chart::Column - phpMan

NAME
    Column - A writer class for Excel Column charts.

SYNOPSIS
    To create a simple Excel file with a Column 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 => '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 Spreadsheet::WriteExcel. 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 Spreadsheet::WriteExcel::Chart.
    Class specific methods or settings, if any, are explained below.

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

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

        #!/usr/bin/perl -w

        use strict;
        use Spreadsheet::WriteExcel;

        my $workbook  = Spreadsheet::WriteExcel->new( 'chart_column.xls' );
        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', 'Sample 1', 'Sample 2' ];
        my $data = [
            [ 2, 3, 4, 5, 6, 7 ],
            [ 1, 4, 5, 2, 1, 5 ],
            [ 3, 6, 7, 5, 4, 3 ],
        ];

        $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. (Sample 1)
        $chart->add_series(
            name       => 'Sample 1',
            categories => '=Sheet1!$A$2:$A$7',
            values     => '=Sheet1!$B$2:$B$7',
        );

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

        # 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 (cm)' );

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

        __END__
