# Example 2. A minimal chart with user specified categories (X axis)
#            and a series name.
#
my $chart2 = $workbook->add_chart( type => 'bar' );

# Configure the series.
$chart2->add_series(
    categories => '=Sheet1!$A$2:$A$7',
    values     => '=Sheet1!$B$2:$B$7',
    name       => 'Test data series 1',
);

The sample script defines data for the cahrt as under

# Add the worksheet data that the charts will refer to.
my $headings = [ 'Category', 'Values 1', 'Values 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 );

You already have data from database, there is no more mapping left

How do I map my data that is retrieved from the database to the chart ?

Do you have microsoft excel installed? Have you ever created a chart using microsoft excel? Have you read http://search.cpan.org/dist/Spreadsheet-WriteExcel/lib/Spreadsheet/WriteExcel.pm#Cell notation

I suggest you drop what you're doing and create a chart using the GUI tools so you can see what is involved

I don't have excel so I cant help

$worksheet = $workbook->add_worksheet("Population Chart");
$worksheet->add_write_handler(qr[\w], \&store_string_widths);
my $chart1 = $workbook->add_chart( type => 'bar', embedded => 1 );

# Configure the series.
$chart1->add_series(
      categories => '=Summary!$A$2:$A$row',
      values     => '=Summary!$G$2:$G$row',
      name       => 'World Population',
      );

# Add another series.
$chart1->add_series(
     categories => '=Summary!$A$2:$A$row',
     values     => '=Summary!$F$2:$F$row',
     name       => 'World Surface Area',
     );

# Add some labels.
$chart1->set_title( name => 'Results of Population analysis' );
$chart1->set_x_axis( name => 'Countries' );
$chart1->set_y_axis( name => 'Population' );

# Insert the chart into the main worksheet.
$worksheet->insert_chart( 'A2', $chart1 );
autofit_columns($worksheet);
