SYNOPSIS

9       To create a simple Excel file with a Bar 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 => 'bar' );
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 );
35
36           __END__

DESCRIPTION

39       This module implements Bar charts for Spreadsheet::WriteExcel. The
40       chart object is created via the Workbook "add_chart()" method:
41
42           my $chart = $workbook->add_chart( type => 'bar' );
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_x_axis();
49           $chart->set_y_axis();
50           $chart->set_title();
51
52       These methods are explained in detail in
53       Spreadsheet::WriteExcel::Chart. Class specific methods or settings, if
54       any, are explained below.
55

Bar Chart Methods

57       There aren't currently any bar chart specific methods. See the TODO
58       section of Spreadsheet::WriteExcel::Chart.

EXAMPLE

61       Here is a complete example that demonstrates most of the available
62       features when creating a chart.
63
64           #!/usr/bin/perl -w
65
66           use strict;
67           use Spreadsheet::WriteExcel;
68
69           my $workbook  = Spreadsheet::WriteExcel->new( 'chart_bar.xls' );
70           my $worksheet = $workbook->add_worksheet();
71           my $bold      = $workbook->add_format( bold => 1 );
72
73           # Add the worksheet data that the charts will refer to.
74           my $headings = [ 'Number', 'Sample 1', 'Sample 2' ];
75           my $data = [
76               [ 2, 3, 4, 5, 6, 7 ],
77               [ 1, 4, 5, 2, 1, 5 ],
78               [ 3, 6, 7, 5, 4, 3 ],
79           ];
80
81           $worksheet->write( 'A1', $headings, $bold );
82           $worksheet->write( 'A2', $data );
83
84           # Create a new chart object. In this case an embedded chart.
85           my $chart = $workbook->add_chart( type => 'bar', embedded => 1 );
86
87           # Configure the first series. (Sample 1)
88           $chart->add_series(
89               name       => 'Sample 1',
90               categories => '=Sheet1!$A$2:$A$7',
91               values     => '=Sheet1!$B$2:$B$7',
92           );
93
94           # Configure the second series. (Sample 2)
95           $chart->add_series(
96               name       => 'Sample 2',
97               categories => '=Sheet1!$A$2:$A$7',
98               values     => '=Sheet1!$C$2:$C$7',
99           );
100
101           # Add a chart title and some axis labels.
102           $chart->set_title ( name => 'Results of sample analysis' );
103           $chart->set_x_axis( name => 'Test number' );
104           $chart->set_y_axis( name => 'Sample length (cm)' );
105
106           # Insert the chart into the worksheet (with an offset).
107           $worksheet->insert_chart( 'D2', $chart, 25, 10 );
