Help : Delphi TQuery and TTable data to Excel Charts?(Delphi3 and Oracle7.3)

(OLE/Com/DCom )

I would like to find-out how to create Excel Charts using OLE/Com/DCom which
work, from data I have in TDatasets.
Is there material, examples ...etc that one can use to see how to
archive something like that?

1. Make intance of Excel and embed it in a TPanel(with OLEContainer maybe on
the panel);
2. Create Excel Chart based on the data in TDataset;
3. Display the chart. (I f possible with the those tabs sheets of excel)

Thanks in advance...
