Spreadsheet::WriteExcel::Chart::Area.3pm

NAME

Area - A writer class for Excel Area charts.

SYNOPSIS

To create a simple Excel file with a Area chart using Spreadsheet::WriteExcel:

     #!/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 => '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__
 
 

DESCRIPTION

This module implements Area charts for Spreadsheet::WriteExcel. The chart object is created via the Workbook "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 Spreadsheet::WriteExcel::Chart. Class specific methods or settings, if any, are explained below.

Area Chart Methods

There aren't currently any area chart specific methods. 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.

     #!/usr/bin/perl -w
 
     use strict;
     use Spreadsheet::WriteExcel;
 
     my $workbook  = Spreadsheet::WriteExcel->new( 'chart_area.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 => 'area', 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 );
 
     __END__
