Creating Excel Chart and Embedding it in Presentation as OLE Object

Required Steps

Following sequence of steps is required to create and embed an Excel Chart as an OLE Object in the PowerPoint Slide:

  1. Create an Excel Chart using Aspose.Cells for C++.# Set the OLE size of the Excel Chart. using Aspose.Cells for C++.# Get the image of the Excel Chart with Aspose.Cells for C++.# Embed the Excel Chart as an OLE Object inside PPTX presentation using Aspose.Slides for C++.# Replace the object changed image with the image obtained in step 3 to cater Object Changed Issue# Write the output presentation to disk in PPTX format

Implementation of the Required Steps

The implementation of the above steps in C# and Visual Basic is as under:


 public static void Run()public static void Run()


    //Step - 1: Create an excel chart using Aspose.Cells


    //Create a workbook

    Aspose.Cells.Workbook wb = new Aspose.Cells.Workbook();

    //Add an excel chart

    int chartRows = 55;

    int chartCols = 25;

    int chartSheetIndex = AddExcelChartInWorkbook(wb, chartRows, chartCols);

    //Step - 2: Set the OLE size of the chart. using Aspose.Cells


    wb.Worksheets.SetOleSize(0, chartRows, 0, chartCols);

    //Step - 3:	Get the image of the chart with Aspose.Cells


    Bitmap imgChart = wb.Worksheets[chartSheetIndex].Charts[0].ToImage();

    //Save the workbook to stream

    MemoryStream wbStream = wb.SaveToStream();

    //Step - 4  AND 5


    //Step - 4: Embed the chart as an OLE object inside .ppt presentation using Aspose.Slides


    //Step - 5: Replace the object changed image with the image obtained in step 3 to cater Object Changed Issue


    //Create a presentation

    Presentation pres = new Presentation();

    ISlide sld = pres.Slides[0];

    //Add the workbook on slide

    AddExcelChartInPresentation(pres, sld, wbStream, imgChart);

    //Step - 6: Write the output presentation on disk


    pres.Save("OutputChart.pptx", Aspose.Slides.Export.SaveFormat.Pptx);

    //Array of cell data

    int[] cellsValue = new int[]








    //Add a new worksheet to populate cells with data

    int dataSheetIdx = wb.Worksheets.Add();

    Aspose.Cells.Worksheet dataSheet = wb.Worksheets[dataSheetIdx];

    string sheetName = "DataSheet";

    dataSheet.Name = sheetName;

    //Populate DataSheet with data

    for (int i = 0; i < cellsName.Length; i++)


        string cellName = cellsName[i];

        int cellValue = cellsValue[i];



    //Add a chart sheet

    int chartSheetIdx = wb.Worksheets.Add(Aspose.Cells.SheetType.Chart);

    Aspose.Cells.Worksheet chartSheet = wb.Worksheets[chartSheetIdx];

    chartSheet.Name = "ChartSheet";

    //Add a chart in ChartSheet with data series from DataSheet

    int chartIdx = chartSheet.Charts.Add(Aspose.Cells.Charts.ChartType.Column, 0, chartRows, 0, chartCols);

    Aspose.Cells.Charts.Chart chart = chartSheet.Charts[chartIdx];

    chart.NSeries.Add(sheetName + "!A1:E1", false);

    chart.NSeries.Add(sheetName + "!A2:E2", false);

    chart.NSeries.Add(sheetName + "!A3:E3", false);

    chart.NSeries.Add(sheetName + "!A4:E4", false);

    //Set ChartSheet an active sheet

    wb.Worksheets.ActiveSheetIndex = chartSheetIdx;

    return chartSheetIdx;


static void AddExcelChartInPresentation(Presentation pres, ISlide sld, Stream wbStream, Bitmap imgChart)


    float oleWidth = pres.SlideSize.Size.Width;

    float oleHeight = pres.SlideSize.Size.Height;

    int x = 0;

    byte[] chartOleData = new byte[wbStream.Length];

    wbStream.Position = 0;

    wbStream.Read(chartOleData, 0, chartOleData.Length);

    IOleObjectFrame oof = null;

    oof = sld.Shapes.AddOleObjectFrame(x, 0, oleWidth, oleHeight, "Excel.Sheet.8", chartOleData);

    oof.SubstitutePictureFormat.Picture.Image = pres.Images.AddImage((System.Drawing.Image)imgChart);
