SYNOPSIS

9       To create a simple Excel file with a Pie chart using
10       Spreadsheet::WriteExcel:
11
12           #!/usr/bin/perl -w
13
14           use strict;
15           use Spreadsheet::WriteExcel;
16
17           my $workbook  = Spreadsheet::WriteExcel->new( 'chart.xls' );
18           my $worksheet = $workbook->add_worksheet();
19
20           my $chart     = $workbook->add_chart( type => 'pie' );
21
22           # Configure the chart.
23           $chart->add_series(
24               categories => '=Sheet1!$A$2:$A$7',
25               values     => '=Sheet1!$B$2:$B$7',
26           );
27
28           # Add the worksheet data the chart refers to.
29           my $data = [
30               [ 'Category', 2, 3, 4, 5, 6, 7 ],
31               [ 'Value',    1, 4, 5, 2, 1, 5 ],
32           ];
33
34           $worksheet->write( 'A1', $data );

36           __END__

DESCRIPTION

39       This module implements Pie charts for Spreadsheet::WriteExcel. The
40       chart object is created via the Workbook add_chart() method:
41
42           my $chart = $workbook->add_chart( type => 'pie' );
43
44       Once the object is created it can be configured via the following
45       methods that are common to all chart classes:
46
47           $chart->add_series();
48           $chart->set_title();
49
50       These methods are explained in detail in
51       Spreadsheet::WriteExcel::Chart. Class specific methods or settings, if
52       any, are explained below.
53

Pie Chart Methods

55       There aren't currently any pie chart specific methods. See the TODO
56       section of Spreadsheet::WriteExcel::Chart.
57
58       A Pie chart doesn't have an X or Y axis so the following common chart
59       methods are ignored.
60
61           $chart->set_x_axis();
62           $chart->set_y_axis();
63

EXAMPLE

65       Here is a complete example that demonstrates most of the available
66       features when creating a chart.
67
68           #!/usr/bin/perl -w
69
70           use strict;
71           use Spreadsheet::WriteExcel;
72
73           my $workbook  = Spreadsheet::WriteExcel->new( 'chart_pie.xls' );
74           my $worksheet = $workbook->add_worksheet();
75           my $bold      = $workbook->add_format( bold => 1 );
76
77           # Add the worksheet data that the charts will refer to.
78           my $headings = [ 'Category', 'Values' ];
79           my $data = [
80               [ 'Apple', 'Cherry', 'Pecan' ],
81               [ 60,       30,       10     ],
82           ];
83
84           $worksheet->write( 'A1', $headings, $bold );
85           $worksheet->write( 'A2', $data );
86
87           # Create a new chart object. In this case an embedded chart.
88           my $chart = $workbook->add_chart( type => 'pie', embedded => 1 );
89
90           # Configure the series.
91           $chart->add_series(
92               name       => 'Pie sales data',
93               categories => '=Sheet1!$A$2:$A$4',
94               values     => '=Sheet1!$B$2:$B$4',
95           );
96
97           # Add a title.
98           $chart->set_title( name => 'Popular Pie Types' );
99
100
101           # Insert the chart into the worksheet (with an offset).
102           $worksheet->insert_chart( 'C2', $chart, 25, 10 );
103
104           __END__
