Excel::Writer::XLSX::Chart::Pie(3pm) User Contributed Perl Documentation Excel::Writer::XLSX::Chart::Pie(3pm) NAME
Pie - A class for writing Excel Pie charts. SYNOPSIS
To create a simple Excel file with a Pie 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 => 'pie' ); # 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 Pie charts for Excel::Writer::XLSX. The chart object is created via the Workbook "add_chart()" method: my $chart = $workbook->add_chart( type => 'pie' ); 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_title(); These methods are explained in detail in Excel::Writer::XLSX::Chart. Class specific methods or settings, if any, are explained below. Pie Chart Methods There aren't currently any pie chart specific methods. See the TODO section of Excel::Writer::XLSX::Chart. A Pie chart doesn't have an X or Y axis so the following common chart methods are ignored. $chart->set_x_axis(); $chart->set_y_axis(); 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_pie.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 = [ 'Category', 'Values' ]; my $data = [ [ 'Apple', 'Cherry', 'Pecan' ], [ 60, 30, 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 => 'pie', embedded => 1 ); # Configure the series. Note the use of the array ref to define ranges: # [ $sheetname, $row_start, $row_end, $col_start, $col_end ]. $chart->add_series( name => 'Pie sales data', categories => [ 'Sheet1', 1, 3, 0, 0 ], values => [ 'Sheet1', 1, 3, 1, 1 ], ); # Add a title. $chart->set_title( name => 'Popular Pie Types' ); # 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( 'C2', $chart, 25, 10 ); __END__ AUTHOR
