Something like this, for a headup:
my $workbook = Spreadsheet::WriteExcel->new('data.xls');
# Add a worksheet
my $worksheet = $workbook->add_worksheet('data');
$worksheet->write_row( $. - 1, 0, [split] ) while <DATA>;
my $chart5 = $workbook->add_chart( type => 'line', embedded => 1 );
# Configure the series.
categories => '=data!$A$2:$A$7',
values => '=data!$B$2:$B$7',
name => 'Test data series 1',
# Add some labels.
$chart5->set_title( name => 'Results of sample analysis' );
$chart5->set_x_axis( name => 'Sample number' );
$chart5->set_y_axis( name => 'Sample length (cm)' );
# Insert the chart into the main worksheet.
$worksheet->insert_chart( 'E2', $chart5 );
