Microsoft Graph Library - Custom Chart

Hello everybody,

I am using Microsoft Graph library to draw certain graphs bu the graph which is shown here in the image is not found in the library. I am using this code to add the graph.

Code:

---

objChart = (Graph.Chart) objSlide.Shapes.AddOLEObject(40,120,650,260,
                                                "MSGraph.Chart.8", "", MsoTriState.msoFalse, "", 0, "",
                                                MsoTriState.msoFalse).OLEFormat.Object;
                                        // Here I specify chart type
                                        objChart.ChartType = Graph.XlChartType.xlColumnStacked;

---

In the actual graph, I can find it by selecting Stacked Column from standard charts and Floating Bars from the custom charts.

How do I find it with code ??

Thanks.
