bdoydie has asked for the wisdom of the Perl Monks concerning the following question:

Hi I have a perl script at the moment which gathers the sar stats for last week and writes them into an excel spreadsheet, i then manually turn these into a chart, I am trying to automate this so the perl script creates the chart aswell, I need to have 1 worksheet with the data and 1 worksheet with the chart, here is what I have so far but its not working: 
#
# Generate Excel Spreadsheet
#

my $workbook = Spreadsheet::WriteExcel->new("$filename");
my $worksheet = $workbook->add_worksheet('cpu_stats');
my $worksheet2 = $workbook->add_worksheet('chart 1');
my $chart = $workbook->add_chart(type => 'line');

# Write header into worksheet
my @header = ('00:00:00','%usr','%sys','%wio','%idle');
$worksheet->write_row(0,0,\@header);

# Write data into worksheet
$worksheet->write('A2',\@data);

# Add worksheet data to the chart
$chart->add_series(
        categories => '=$worksheet!$B$1:$E$1',
        values     => '=$worksheet!$A$1:$E$1450',
        name       => 'chart1',
);

# Add chart labels
$chart->set_title (name=> '$host Performance Chart for Week Ending $we
+ek_ending');
$chart->set_x_axis (name=> 'Time 24(HR)');
$chart->set_y_axis (name=> 'Percentage');

# Insert chart into worksheet2
$worksheet2->insert_chart ('A1', $chart);

# Close workbook
$workbook->close;

    Hi bdoydie,

    Something like this, for a headup:

    #!/usr/bin/perl
use warnings;
use strict;

use Spreadsheet::WriteExcel;

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.
$chart5->add_series(
    categories => '=data!$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 );

__DATA__
Value1    Value2
1    5
2    0
3    30
4    15
5    75

    Please, take your time to check Spreadsheet::WriteExcel::Examples for more details, it will answer your questions.

    If you tell me, I'll forget.
    If you show me, I'll remember.
    if you involve me, I'll understand.

    For your initial problem, I think you may need to concatenate and interpolate your '$worksheet!' hash values.

    $chart->add_series(
        categories => '='."$worksheet".'!$B$1:$E$1',
        values     => '='."$worksheet".'!$A$1:$E$1450',
        name       => 'chart1',
);

      Instead of hard coding as " categories => '='."$worksheet".'!$B$1:$E$1' ", Can we make it dynamic to select the range of cells to plot the chart? Any idea how to make it dynamic?
[reply]

        Making the range dynamic is as easy as constructing the appropriate string for the range.

        Have a look at Re^3: Win32::Ole excel external data range, in which I show the use of dynamic ranges. It does other things too (it's answering a different question), but I think it's reasonably clear.

    I also want wanting to know is there a way to edit the properties of the chart? I want a line chart but without markers so it is easier to read can this be done?
