Excel::Writer::XLSX::Chart::Radar (3pm)

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 );

This module implements Radar charts for Excel::Writer::XLSX. The chart object is created via the Workbook \*(C`add_chart()\*(C' 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 \*(C`Radar\*(C' chart module also supports the following sub-types:

with_markers filled

These can be specified at creation time via the \*(C`add_chart()\*(C' 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 );
