Excel::Writer::XLSX::Chart::Radar(3) User Contributed Perl Documentation Excel::Writer::XLSX::Chart::Radar(3)
 

Radar - A class for writing Excel Radar charts.

To create a simple Excel file with a Radar 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 => 'radar' );
    # 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__

This module implements Radar charts for Excel::Writer::XLSX. The chart object is created via the Workbook "add_chart()" method:
    my $chart = $workbook->add_chart( type => 'radar' );
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.

The "Radar" chart module also supports the following sub-types:
    with_markers
    filled
These can be specified at creation time via the "add_chart()" Worksheet method:
    my $chart = $workbook->add_chart( type => 'radar', subtype => 'filled' );

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_radar.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 ],
        [ 30, 60, 70, 50, 40, 30 ],
        [ 25, 40, 50, 30, 50, 40 ],
    ];
    $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 => 'radar', 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. Colors with white outline and shadow.
    $chart->set_style( 10 );
    # Insert the chart into the worksheet (with an offset).
    $worksheet->insert_chart( 'D2', $chart, 25, 10 );
    __END__
