NAME

6       Bar - A class for writing Excel Bar charts.

SYNOPSIS

9       To create a simple Excel file with a Bar chart using
10       Excel::Writer::XLSX:
11
12           #!/usr/bin/perl
13
14           use strict;
15           use warnings;
16           use Excel::Writer::XLSX;
17
18           my $workbook  = Excel::Writer::XLSX->new( 'chart.xlsx' );
19           my $worksheet = $workbook->add_worksheet();
20
21           my $chart     = $workbook->add_chart( type => 'bar' );
22
23           # Configure the chart.
24           $chart->add_series(
25               categories => '=Sheet1!$A$2:$A$7',
26               values     => '=Sheet1!$B$2:$B$7',
27           );
28
29           # Add the worksheet data the chart refers to.
30           my $data = [
31               [ 'Category', 2, 3, 4, 5, 6, 7 ],
32               [ 'Value',    1, 4, 5, 2, 1, 5 ],
33           ];
34
35           $worksheet->write( 'A1', $data );
36
37           __END__

DESCRIPTION

40       This module implements Bar charts for Excel::Writer::XLSX. The chart
41       object is created via the Workbook "add_chart()" method:
42
43           my $chart = $workbook->add_chart( type => 'bar' );
44
45       Once the object is created it can be configured via the following
46       methods that are common to all chart classes:
47
48           $chart->add_series();
49           $chart->set_x_axis();
50           $chart->set_y_axis();
51           $chart->set_title();
52
53       These methods are explained in detail in Excel::Writer::XLSX::Chart.
54       Class specific methods or settings, if any, are explained below.
55

Bar Chart Subtypes

57       The "Bar" chart module also supports the following sub-types:
58
59           stacked
60           percent_stacked
61
62       These can be specified at creation time via the "add_chart()" Worksheet
63       method:
64
65           my $chart = $workbook->add_chart( type => 'bar', subtype => 'stacked' );
66

EXAMPLE

68       Here is a complete example that demonstrates most of the available
69       features when creating a chart.
70
71           #!/usr/bin/perl
72
73           use strict;
74           use warnings;
75           use Excel::Writer::XLSX;
76
77           my $workbook  = Excel::Writer::XLSX->new( 'chart_bar.xlsx' );
78           my $worksheet = $workbook->add_worksheet();
79           my $bold      = $workbook->add_format( bold => 1 );
80
81           # Add the worksheet data that the charts will refer to.
82           my $headings = [ 'Number', 'Batch 1', 'Batch 2' ];
83           my $data = [
84               [ 2,  3,  4,  5,  6,  7 ],
85               [ 10, 40, 50, 20, 10, 50 ],
86               [ 30, 60, 70, 50, 40, 30 ],
87
88           ];
89
90           $worksheet->write( 'A1', $headings, $bold );
91           $worksheet->write( 'A2', $data );
92
93           # Create a new chart object. In this case an embedded chart.
94           my $chart = $workbook->add_chart( type => 'bar', embedded => 1 );
95
96           # Configure the first series.
97           $chart->add_series(
98               name       => '=Sheet1!$B$1',
99               categories => '=Sheet1!$A$2:$A$7',
100               values     => '=Sheet1!$B$2:$B$7',
101           );
102
103           # Configure second series. Note alternative use of array ref to define
104           # ranges: [ $sheetname, $row_start, $row_end, $col_start, $col_end ].
105           $chart->add_series(
106               name       => '=Sheet1!$C$1',
107               categories => [ 'Sheet1', 1, 6, 0, 0 ],
108               values     => [ 'Sheet1', 1, 6, 2, 2 ],
109           );
110
111           # Add a chart title and some axis labels.
112           $chart->set_title ( name => 'Results of sample analysis' );
113           $chart->set_x_axis( name => 'Test number' );
114           $chart->set_y_axis( name => 'Sample length (mm)' );
115
116           # Set an Excel chart style. Blue colors with white outline and shadow.
117           $chart->set_style( 11 );
118
119           # Insert the chart into the worksheet (with an offset).
120           $worksheet->insert_chart( 'D2', $chart, 25, 10 );
121
