=head1 NAME
Area - A class for writing Excel Area charts.
=head1 SYNOPSIS
To create a simple Excel file with a Area chart using Excel::Writer::XLSX:
#!/usr/bin/perl
use strict;
use warnings;
use Excel::Writer::XLSX;
my $workbook = Excel::Writer::XLSX->new( 'chart.xlsx' );
my $worksheet = $workbook->add_worksheet();
my $chart = $workbook->add_chart( type => 'area' );
# Configure the chart.
$chart->add_series(
categories => '=Sheet1!$A$2:$A$7',
values => '=Sheet1!$B$2:$B$7',
);
# Add the worksheet data the chart refers to.
my $data = [
[ 'Category', 2, 3, 4, 5, 6, 7 ],
[ 'Value', 1, 4, 5, 2, 1, 5 ],
];
$worksheet->write( 'A1', $data );
__END__
=head1 DESCRIPTION
This module implements Area charts for L<Excel::Writer::XLSX>. The chart object is created via the Workbook C<add_chart()> method:
my $chart = $workbook->add_chart( type => 'area' );
Once the object is created it can be configured via the following methods that are common to all chart classes:
$chart->add_series();
$chart->set_x_axis();
$chart->set_y_axis();
$chart->set_title();
These methods are explained in detail in L<Excel::Writer::XLSX::Chart>. Class specific methods or settings, if any, are explained below.
=head1 Area Chart Methods
There aren't currently any area chart specific methods. See the TODO section of L<Excel::Writer::XLSX::Chart>.
=head1 EXAMPLE
Here is a complete example that demonstrates most of the available features when creating a chart.
#!/usr/bin/perl
use strict;
use warnings;
use Excel::Writer::XLSX;
my $workbook = Excel::Writer::XLSX->new( 'chart_area.xlsx' );
my $worksheet = $workbook->add_worksheet();
my $bold = $workbook->add_format( bold => 1 );
# Add the worksheet data that the charts will refer to.
my $headings = [ 'Number', 'Batch 1', 'Batch 2' ];
my $data = [
[ 2, 3, 4, 5, 6, 7 ],
[ 40, 40, 50, 30, 25, 50 ],
[ 30, 25, 30, 10, 5, 10 ],
];
$worksheet->write( 'A1', $headings, $bold );
$worksheet->write( 'A2', $data );
# Create a new chart object. In this case an embedded chart.
my $chart = $workbook->add_chart( type => 'area', embedded => 1 );
# Configure the first series.
$chart->add_series(
name => '=Sheet1!$B$1',
categories => '=Sheet1!$A$2:$A$7',
values => '=Sheet1!$B$2:$B$7',
);
# Configure second series. Note alternative use of array ref to define
# ranges: [ $sheetname, $row_start, $row_end, $col_start, $col_end ].
$chart->add_series(
name => '=Sheet1!$C$1',
categories => [ 'Sheet1', 1, 6, 0, 0 ],
values => [ 'Sheet1', 1, 6, 2, 2 ],
);
# Add a chart title and some axis labels.
$chart->set_title ( name => 'Results of sample analysis' );
$chart->set_x_axis( name => 'Test number' );
$chart->set_y_axis( name => 'Sample length (mm)' );
# Set an Excel chart style. Blue colors with white outline and shadow.
$chart->set_style( 11 );
# Insert the chart into the worksheet (with an offset).
$worksheet->insert_chart( 'D2', $chart, 25, 10 );
