Hy,
i'm using c# to create a powerPoint presentation that contains charts. I've added the chart(s) using Graph.Chart, it looks like this:
Code:
 Graph.Chart objChart = (Graph.Chart)objSlide.Shapes.AddOLEObject(xx, yy, 250, 180,
                    "MSGraph.Chart.8", "", MsoTriState.msoFalse, "", 0, "", MsoTriState.msoFalse).OLEFormat.Object;
            objChart.ChartType = Graph.XlChartType.xl3DColumnClustered;
...
