.SH "NAME"
Pie \- A writer class for Excel Pie charts.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
To create a simple Excel file with a Pie chart using Spreadsheet::WriteExcel:
.PP
.Vb 1
\&    #!/usr/bin/perl \-w
\&
\&    use strict;
\&    use Spreadsheet::WriteExcel;
\&
\&    my $workbook  = Spreadsheet::WriteExcel\->new( \*(Aqchart.xls\*(Aq );
\&    my $worksheet = $workbook\->add_worksheet();
\&
\&    my $chart     = $workbook\->add_chart( type => \*(Aqpie\*(Aq );
\&
\&    # Configure the chart.
\&    $chart\->add_series(
\&        categories => \*(Aq=Sheet1!$A$2:$A$7\*(Aq,
\&        values     => \*(Aq=Sheet1!$B$2:$B$7\*(Aq,

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module implements Pie charts for Spreadsheet::WriteExcel. The chart object is created via the Workbook \f(CW\*(C`add_chart()\*(C'\fR method:
.PP
.Vb 1
\&    my $chart = $workbook\->add_chart( type => \*(Aqpie\*(Aq );
.Ve
.PP
Once the object is created it can be configured via the following methods that are common to all chart classes:
.PP
.Vb 2
\&    $chart\->add_series();
\&    $chart\->set_title();
.Ve
.PP
These methods are explained in detail in Spreadsheet::WriteExcel::Chart. Class specific methods or settings, if any, are explained below.
.SH "Pie Chart Methods"
.IX Header "Pie Chart Methods"
There aren't currently any pie chart specific methods. See the \s-1TODO\s0 section of Spreadsheet::WriteExcel::Chart.
.PP
A Pie chart doesn't have an X or Y axis so the following common chart methods are ignored.
.PP
.Vb 2
\&    $chart\->set_x_axis();
\&    $chart\->set_y_axis();
.Ve
.SH "EXAMPLE"
.IX Header "EXAMPLE"
Here is a complete example that demonstrates most of the available features when creating a chart.
