I'm not a Win32::OLE user, but that loose curly bracket looks suspect:

$chart->ChartType} = xl3DColumnClustered;

I tried to throw your code into a file like this:

use strict;
use warnings;
use Win32::OLE;
my ($vtfalse,$sheet);
# Create the chart #
my $chart = $sheet->ChartObjects->Add(1, 175, 457, 300);
$chart->ChartType = 'xl3DColumnClustered';
$chart->Chart->ChartWizard({Source =>$sheet->Range("D5:D12")});
$chart->Chart->SeriesCollection(1)->{Values}=$sheet->Range("D5:D12");
$chart->Chart->SeriesCollection(1)->{XValues}=$sheet->Range("B5:B12");
$chart->Chart->SeriesCollection(1)->{Values}=$sheet->Range("D5:D12");
$chart->Chart->SeriesCollection(1)->{Name}=$sheet->Range("B5:B12");
$chart->Chart->{HasLegend} = $vtfalse;
$chart->Chart->{HasDataTable} = $vtfalse;
$chart->Chart->SeriesCollection(1)->{HasDataLabels} = 1;

but I still get errors.

Can't call method "ChartObjects" on an undefined value at K:\Desktop\3
+d-chart.pl

Guess I'm missing something else. Can you post some minimal complete code that illustrates your problem?

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
