Excel:...Scatter(3pm)

💖 NAME 💖

Scatter — bestie, it's a whole class for writing Excel Scatter charts ✨ like, it literally writes scatter charts into Excel files for you, no cap.

---

🌸 SYNOPSIS 🌸

okay so if you wanna whip up a simple Excel file with a Scatter chart using Excel::Writer::XLSX, this is the vibe:

#!/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 => 'scatter' );

# 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__

🦋 that's it, that's the whole thing, iconic behavior honestly.

✨ DESCRIPTION ✨

So this module implements Scatter charts for Excel::Writer::XLSX 💅 and you make the chart object through the Workbook add_chart() method, like this:

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

Once you've got the object, you can configure it with these methods, which are the shared besties across all the chart classes:

$chart->add_series();
$chart->set_x_axis();
$chart->set_y_axis();
$chart->set_title();

These are explained in full detail in Excel::Writer::XLSX::Chart, so go check that out fr. Any class-specific methods or settings — if there even are any — are explained right below 👇

🎀 Scatter Chart Subtypes 🎀

The "Scatter" chart module also supports these sub-types, slay:

markers_only (the default)
straight_with_markers
straight
smooth_with_markers
smooth

And you can specify them at creation time through the add_chart() Worksheet method, like so:

my $chart = $workbook->add_chart(
    type    => 'scatter',
    subtype => 'straight_with_markers'
);

🔥 EXAMPLE 🔥

Here's a complete example showing off most of the available features when you're creating a chart. It's giving main character energy:

#!/usr/bin/perl

use strict;
use warnings;
use Excel::Writer::XLSX;

my $workbook  = Excel::Writer::XLSX->new( 'chart_scatter.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 ],
    [ 10, 40, 50, 20, 10, 50 ],
    [ 30, 60, 70, 50, 40, 30 ],

];

$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 => 'scatter', 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. Colors with white outline and shadow.
$chart->set_style( 10 );

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

__END__

👑 go off honestly.
