I have tested your issue with latest version v6.0.1.4 and it works fine. Please try the latest version:Aspose.Cells for .NET v6.0.1.4
Here is my sample code and you can find attach the output PDF file. The data labels of the series are not shaded with white background color, it works fine.
Did you check my attached output PDF file, it is fine tuned. The data labels are not rendered with white background color, I opened the file into Acrobat Reader. I used the code mentioned in my previous post. The chart is rendered based on the data source filled with dummy data.
We appreciate if you could create a simple console application, zip it and post it here to show the issue. Also give us screen shots for the issue area. We will check it soon.
I have found the issue using the code sample in your project with your template file. The chart data labels are rendered with white background. I have logged an issue with an id: CELLSNET-29840. We will figure it out soon.
Well, the chart labels are transparent over the background. Any ways, we have decided to to remove the transparent color. So we think we will solve it soon.
Thanks for the information, but, we might not be using transparent colors for the charts in the older version e.g 5.3.3. Anyways, thanks for further help.
Hi, using the code below to save the pdf file, the problem persist yet.
The difference is in the option "pdfSaveOptions.Compliance = Aspose.Cells.Rendering.PdfCompliance.PdfA1b;". When I don't use it, the charts are fine, but the texts are bold. So, I have to use this option.
C#
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
