NAME

Area - A writer class for Excel Area charts.

CONTENTS

SYNOPSIS

To create a simple Excel file with a Area 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 => area );

    # 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 Area charts for Spreadsheet::WriteExcel. The chart object is created via the Workbook add_chart() method:



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



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.

Area Chart Methods

There aren’t currently any area 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_area.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 => area, 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__
