NAME
       Pie - A writer class for Excel Pie charts.

SYNOPSIS
       To create a simple Excel file with a Pie 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 => 'pie' );

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

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

       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_title();

       These methods are explained in detail in Spreadsheet::WriteExcel::Chart. Class specific
       methods or settings, if any, are explained below.

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

       A Pie chart doesn't have an X or Y axis so the following common chart methods are ignored.

           $chart->set_x_axis();
           $chart->set_y_axis();

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_pie.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 = [ 'Category', 'Values' ];
           my $data = [
               [ 'Apple', 'Cherry', 'Pecan' ],
               [ 60,       30,       10     ],
           ];

           $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 => 'pie', embedded => 1 );

           # Configure the series.
           $chart->add_series(
               name       => 'Pie sales data',
               categories => '=Sheet1!$A$2:$A$4',
               values     => '=Sheet1!$B$2:$B$4',
           );

           # Add a title.
           $chart->set_title( name => 'Popular Pie Types' );

           # Insert the chart into the worksheet (with an offset).
           $worksheet->insert_chart( 'C2', $chart, 25, 10 );

           __END__
