6 Bar - A writer class for Excel Bar charts.

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__

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
57 There aren't currently any bar chart specific methods. See the TODO
58 section of Spreadsheet::WriteExcel::Chart.
59
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 );
