I see the OverflowException error thrown. Is there an argument or load option I can pass to help mitigate this problem?
After an initial test, I am able to reproduce the issue as you mentioned by using your sample with PPTX file. I found an exception “System.OverflowException: ‘Value was either too large or too small for an Int32’” on Chart.Calculate() method.

Hi, i am having the same error when “Chart.ToImage()”.
Is there anyway i can do a local test of the fix? I am currently using version 23.4.0
TIA, Frank
The fix is not published/released yet. Anyways, could you please share your template Excel file (please zip it prior attaching) and sample code to reproduce the issue. We will check it soon.
I am unable to produce an example .xlsx with the error, it is not persistent.
So as soon as the fix is around, i will do some testing and report back
