Hi Saurabh,

I have tried to understand the issue shared by you but the information that you have shared is not enough to reproduce the issue on my end. It will be really nice if you may please share a working project code with us for further investigation on our end.

Thanks and Regards,

Ok… find the code sample attached with this reply

Hi Saurabh,

Thanks for sharing the requested information. I have worked with the code snippet shared by you and have been able to reproduce the issue as shared by you. An issue with ID 30416 has been created in our issue tracking system to further investigate that whether the issue belongs to Aspose.Slides for .NET or Aspose.Cells for .NET. We will share further information with you once the investigation is completed and issue is resolved.

We are sorry for your inconvenience,

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

Is there any update on this issue? We are using this component in the production environment and the customer in trouble because of this issue.

Hi Mudassir,

I used new version of dll you given me (Aspose.Cells for .NET v7.0.1.7) in my application. I am not getting memory error but total labels are not going on top of bar graph.
Functionality of below line is not working in this version of dll.
ser4.DataLabels.Position = LabelPositionType.OutsideEnd;


Hi Saurabh,

I have worked with Aspose.Slides for .NET 5.6.0 and Aspose.Cells for .NET and have no more observed the issue. For your kind reference, I have attached sample project based on your code snippet for your further kind reference. Please share, if the issue still prevail for you.

Thanks and Regards,

Hi Mudassir,

As I already told you, now i am not getting memory error but now i am unable to put total label on top of stacked chart , its coming inside of stacked chart area.
please check the attached screenshot which i have taken from sample project which you have given me in your last reply.


Hi Saurabh,

I have observed the inconsistency in image attached and like to share that the generated excel sheet also contains the same effect. The issue seems to be on Aspose.Cells end as Aspose.Slides is only responsible for displaying chart in Ole frame and that it is doing correctly. So, with you permission, I am moving this thread to Aspose.Cells forum, where respective support team will help you further in this regard.

Thanks and Regards,


Please try the latest version:
Aspose.Cells for .NET v7.0.1.7 and let us know your results.

If the problem persists, then please provide us you simple sample runnable application replicating the issue along with the source xls/xlsx files if you are using any.

Please remove all your Business, Database and Aspose.Slides dependent code and instead use hardcoded values. It will help us quickly find out and fix the bug at our end.


Yesterday I already tried this version. Mudassir given me this version of dll, its not working for me.
Sample code you can find out in my first post of this thread.


Okay… Check the attached sample code


Thanks for your code. We will let you know after looking into it asap.


I have run the following code based on your code. I have removed all Aspose.Slides and your Business related code and used hard coded values. I got the following output image as attached by me.

Now, please highlight all the problems in a screenshot with red circles and provide me xls/xlsx file with your desired chart which you can create manually using Ms-Excel and post here.

You can also download and correct the out.jpg.xlsx file attached by me manually using Ms-Excel and post here.

Hi mshakeel,

Please check the attachment.
I want totals labels at same position where i have added in excel file. and this chart should be OLEobject when I double click it should go in excel mode and datalabel position should not be change.



I am interested to know, how did you generate using Ms-Excel. Was this automatically generated by Excel or you manually added Textboxes and calculated Sum.

Manually added.


I am afraid, Aspose.Cells can add textboxes inside the chart but can’t calculate the exact position that you want. Rather, Aspose.Cells will give you access to Shape.Left and Shape.Top properties and you will have to adjust the textboxes yourself using these properties.

Please see the following document for your reference.

You can add total label in excel by creating total value on secondary y-axis, and then hiding
the formatting for the bars and secondary y-axis.
