Spreads...art::Bar(3)

💅 NAME 💅

okay so this is Spreads...art::Bar(3), straight outta User Contributed Perl Documentation, and it's literally about Bar charts. Bar is a writer class for Excel Bar charts. That's the vibe. ✨

🌸 SYNOPSIS 🌸

Bestie, if you wanna create a simple Excel file with a Bar chart using Spreadsheet::WriteExcel, this is the exact slay:

#!/usr/bin/perl -w

use strict;
use Spreadsheet::WriteExcel;

my $workbook  = Spreadsheet::WriteExcel->new( 'chart.xls' );
my $worksheet = $workbook->add_worksheet();

my $chart     = $workbook->add_chart( type => 'bar' );

# 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__

✨ DESCRIPTION ✨

This module implements Bar charts for Spreadsheet::WriteExcel. Iconic behavior, honestly. The chart object is created via the Workbook add_chart() method:

my $chart = $workbook->add_chart( type => 'bar' );

Once the object is created, you can configure it with these 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 Spreadsheet::WriteExcel::Chart. Class specific methods or settings, if any, are explained below. 🫶

🎀 Bar Chart Methods 🎀

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

🔥 EXAMPLE 🔥

Here is a complete example that demonstrates most of the available features when creating a chart. It's giving main character energy:

#!/usr/bin/perl -w

use strict;
use Spreadsheet::WriteExcel;

my $workbook  = Spreadsheet::WriteExcel->new( 'chart_bar.xls' );
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', 'Sample 1', 'Sample 2' ];
my $data = [
    [ 2, 3, 4, 5, 6, 7 ],
    [ 1, 4, 5, 2, 1, 5 ],
    [ 3, 6, 7, 5, 4, 3 ],
];

$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 => 'bar', embedded => 1 );

# Configure the first series. (Sample 1)
$chart->add_series(
    name       => 'Sample 1',
    categories => '=Sheet1!$A$2:$A$7',
    values     => '=Sheet1!$B$2:$B$7',
);

# Configure the second series. (Sample 2)
$chart->add_series(
    name       => 'Sample 2',
    categories => '=Sheet1!$A$2:$A$7',
    values     => '=Sheet1!$C$2:$C$7',
);

# 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 (cm)' );

# Insert the chart into the worksheet (with an offset).
$worksheet->insert_chart( 'D2', $chart, 25, 10 );
