S-349: Vulnerabilities in Microsoft Excel
There are multiple remote code execution vulnerabilities in the Excel. An attacker could exploit the vulnerability by opening a specially crafted file which could be hosted on a Web site, or included as an e-mail attachment. The risk is MEDIUM. Depending on the attack scenario, the vulnerability could lead to remote code execution ona user's local Excel client, or it could lead to elevation of privilage within a SharePoint Server.

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

NAME

       Pie - A class for writing Excel Pie charts.

SYNOPSIS

       To create a simple Excel file with a Pie 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 => '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 Excel::Writer::XLSX. 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 Excel::Writer::XLSX::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 Excel::Writer::XLSX::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

	   use strict;
	   use warnings;
	   use Excel::Writer::XLSX;

	   my $workbook  = Excel::Writer::XLSX->new( 'chart_pie.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 = [ '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. Note the use of the array ref to define ranges:
	   # [ $sheetname, $row_start, $row_end, $col_start, $col_end ].
	   $chart->add_series(
	       name	  => 'Pie sales data',
	       categories => [ 'Sheet1', 1, 3, 0, 0 ],
	       values	  => [ 'Sheet1', 1, 3, 1, 1 ],
	   );

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

	   # 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( 'C2', $chart, 25, 10 );

	   __END__
