Dear monks, I use win32::Ole to generate several powerpoint slides with a ms graph within (one graph per slide).
i have no problem to create the graph, setup it and feed the datasheet from a database, but when there's more than one graph in the presentation and when i try to edit a graph in powerpoint, it is resetted ( as if a new graph was inserted with the menu 'Insert->Chart...' ).
It doesn't happen with a single graph on a single slide, the graph can be then correctly edited, the values and the setup i defined in my script are kept. Here's the way i create a new presentation:

###########################################################
#
# sub create_ppt_presentation
#
# create and return a new blank presentation
#
# $title is title for the presentation
#
###########################################################
sub create_ppt_presentation
{
    my ($title) = @_;

    my ($PptApp, $Presentation, $Slide);

    trace("create_ppt_presentation: getting powerpoint.application obj
+ect\n");
    $PptApp  = Win32::OLE-> GetActiveObject('PowerPoint.Application')
    || Win32::OLE-> new('PowerPoint.Application', 'Quit');
    $PptApp-> {Visible} = IS_PPT_VISIBLE;
    $Presentation = $PptApp-> Presentations->Add();

    return ($PptApp, $Presentation);
}

Here's the way i use to create a slide and add a graph within, using the previously created presentation object:

$Slide = $Presentation-> Slides->Add({Index => $position, Layout => pp
+LayoutBlank});
$Slide->{Name} = "test";

$graph_shape = $Slide->Shapes->AddOleObject({
   Left => 10,
   Top => 40,
   Height => 450,
   Width => 650,
   ClassName => "MSGraph.Chart",
   Link => 0});
$graph = $graph_shape->OLEFormat->{Object}; # ms graph chart object

# i can now work with $graph

Here's how i get the datasheet:

    $datasheet = $graph->Application->{DataSheet};
    $datasheet->Cells->ClearContents();
    # i can now feed the datasheet with some datas
    # ...
    
    # after the settings of the datasheet's cells, free graph and data
+sheet
    undef $datasheet;
    undef $graph;

After this, here's how i save the powerpoint presentation.
Note i dont't close presentation object, and quit the powerpoint application object at the end of the script. ( Maybe the issue is here ?? )

   # $Presentaion is the powerpoint presentation object
   $Presentation->SaveAs("c:/test.ppt");

If anyone has an idea about this mysterious reset, i'll be sooo glad to hear it :o)
