#1

Hello ,



I would like to know some things on oleObjectFrame.


  1. Is it compulsory to make the worksheet as chart sheet like
    Dim chartSheetIdx As Integer = wb.Worksheets.Add(SheetType.Chart)
    or we can even add chart in normal worksheet as get the chart from it using
    Dim imgChart As Bitmap = wb.Worksheets(2).Charts(0).ToImage().
  2. I am having a scenario in which i have many charts and each chart is having the data above that only i am attaching a excel file for your reference as step2.xls this excel i have prepare
    using aspose.cells now i want to export all the charts from this excel to PPT
  3. Also if it is compulsory to make the worksheet as chart sheet then can i add multiple chart is that one worksheet or for different chart i have to create different sheets kindly provide me some code reference for this
Kindly revert me as soon as possible

Thanks & Regards

Hi Zaid,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

I like to share that it is not compulsory to use the SheetType.Chart only and you may also use SheetType.WorkSheet as well when creating using Aspose.Cells. Moreover, in Aspose.Slides you are adding excel file as Ole object, so whether the its a chart sheet, data sheet or data sheet with charts, it will display them. So, if the sheet has multiple charts in it that will also be displayed. Hope it clears the concept. The issue here is that you need to set the sheet and ole frame size as they are capable of displaying only limited portion of sheet. If you wish to display the complete sheet in Ole frame then resolution will be too small to view the things. For sake of reference to sheet size and ole frame size, please read this article.

Secondly, I will request Aspose.Cells team to share further response on SheetTypes for your kind reference.

Thanks and Regards,

Hello Muddasir,

In my case i have multiple charts on one sheet and what i want is to displauy each chart on different slides
i dont want full sheet to get display on one slide but on different.

Like can i create different images as
Dim imgChart1 As Bitmap = wb.Worksheets(2).Charts(0).ToImage().
Dim imgChart2 As Bitmap = wb.Worksheets(2).Charts(1).ToImage().
Dim imgChart3 As Bitmap = wb.Worksheets(2).Charts(3).ToImage().
.
.
.
and then export all that images to PPT using different OLE frames

Hi Zaid,

You can access the charts on same sheet and can display then on separate sheets using separate Ole frames. As in example shared by you here you have displayed multiple charts from separate sheets on two different slides. Similarly, You can also access the charts on the same sheets as well as you have mentioned above.

Thanks and Regards,

Dim intsheetcount As Integer = 4

For i = 0 To intsheetcount - 1
Workbook.Worksheets.ActiveSheetIndex = i
Dim wbStream As MemoryStream = Workbook.SaveToStream()
wbStream.Position = 0
Dim imgChart As Bitmap = Workbook.Worksheets(i).Charts(0).ToImage()

You may be right that the issue might be there in Aspose.Slides for .NET 5.8.0 or 5.7.0. But, I have tested created the presentation using Aspose.Slides for .NET 6.1.0 and it works as well when I open the presentation in PowerPoint 2010. I may request you to use try using Aspose.Slides for .NET trial version for instance and if you confirm the issue as resolved then please renew your subscription to avail the feature. Actually, as per company policy, the support is always provided in latest available product version. Please also read this renewal subscription policy for your reference.
