NAME

Stock - A class for writing Excel Stock charts.

CONTENTS

SYNOPSIS

To create a simple Excel file with a Stock chart using Excel::Writer::XLSX:



    #!/usr/bin/perl -w

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

    my $workbook  = Excel::Writer::XLSX->new( chart.xlsx );
    my $worksheet = $workbook->add_worksheet();

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

    # Add a series for each High-Low-Close.
    $chart->add_series(
        categories => =Sheet1!$A$2:$A$6,
        values     => =Sheet1!$B$2:$B$6
    );

    $chart->add_series(
        categories => =Sheet1!$A$2:$A$6,
        values     => =Sheet1!$C$2:$C$6
    );

    $chart->add_series(
        categories => =Sheet1!$A$2:$A$6,
        values     => =Sheet1!$D$2:$D$6
    );

    # Add the worksheet data the chart refers to.
    # ... See the full example below.

    __END__



DESCRIPTION

This module implements Stock charts for Excel::Writer::XLSX. The chart object is created via the Workbook add_chart() method:



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



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.

Stock Chart Methods

There aren’t currently any stock chart specific methods. See the TODO section of Excel::Writer::XLSX::Chart.

The default Stock chart is a High-Low-Close chart. A series must be added for each of these data sources.

EXAMPLE

Here is a complete example that demonstrates most of the available features when creating a Stock chart.



    #!/usr/bin/perl

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

    my $workbook    = Excel::Writer::XLSX->new( chart_stock.xlsx );
    my $worksheet   = $workbook->add_worksheet();
    my $bold        = $workbook->add_format( bold => 1 );
    my $date_format = $workbook->add_format( num_format => dd/mm/yyyy );
    my $chart       = $workbook->add_chart( type => stock, embedded => 1 );


    # Add the worksheet data that the charts will refer to.
    my $headings = [ Date, High, Low, Close ];
    my $data = [

        [ 2007-01-01T, 2007-01-02T, 2007-01-03T, 2007-01-04T, 2007-01-05T ],
        [ 27.2,  25.03, 19.05, 20.34, 18.5 ],
        [ 23.49, 19.55, 15.12, 17.84, 16.34 ],
        [ 25.45, 23.05, 17.32, 20.45, 17.34 ],

    ];

    $worksheet->write( A1, $headings, $bold );

    for my $row ( 0 .. 4 ) {
        $worksheet->write_date_time( $row+1, 0, $data->[0]->[$row], $date_format );
        $worksheet->write( $row+1, 1, $data->[1]->[$row] );
        $worksheet->write( $row+1, 2, $data->[2]->[$row] );
        $worksheet->write( $row+1, 3, $data->[3]->[$row] );

    }

    $worksheet->set_column( A:D, 11 );

    # Add a series for each of the High-Low-Close columns.
    $chart->add_series(
        categories => =Sheet1!$A$2:$A$6,
        values     => =Sheet1!$B$2:$B$6,
    );

    $chart->add_series(
        categories => =Sheet1!$A$2:$A$6,
        values     => =Sheet1!$C$2:$C$6,
    );

    $chart->add_series(
        categories => =Sheet1!$A$2:$A$6,
        values     => =Sheet1!$D$2:$D$6,
    );

    # Add a chart title and some axis labels.
    $chart->set_title ( name => High-Low-Close, );
    $chart->set_x_axis( name => Date, );
    $chart->set_y_axis( name => Share price, );


    $worksheet->insert_chart( E9, $chart );

    __END__
