SYNOPSIS
To create a simple Excel file with a Column 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 => 'column' );
# 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 Column charts for Excel::Writer::XLSX. The chart object is created via the Workbook "add_chart()" method:
my $chart = $workbook->add_chart( type => 'column' );
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 Excel::Writer::XLSX::Chart. Class specific methods or settings, if any, are explained below.
Column Chart Subtypes
The "Column" chart module also supports the following sub-types:
stacked percent_stacked
These can be specified at creation time via the "add_chart()" Worksheet method:
my $chart = $workbook->add_chart( type => 'column', subtype => 'stacked' );
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_column.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 => 'column', 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 ); __END__
