A class for writing excel stock charts.
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_\|_
This module implements Stock charts for Excel::Writer::XLSX. The chart object is created via the Workbook \*(C`add_chart()\*(C' 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.
There aren't currently any stock chart specific methods. See the \s-1TODO\s0 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.
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 );
