Why is there a line in DonutChart's area?

[rickyjessy]

Hello,

I use Excel to generate a DonutChart chart and save it to PDF.

sheet.SaveToPdf(@"D:\ClosedXMLResultDonutChart.pdf");

But why is there a red line in DonutChart's blue area?

Current situation in attachment.

Please help me.

Thanks!

Dear Chen Ricky,

Thank you for your inquiry.
This is a known issue in Free Spire.XLS. Sorry that we have no plan to update the free products.
I have confirmed that the issue did not occur in the latest commercial hotfix Spire.XLS Pack(Hotfix) Version:8.11.6. Please apply it and try again.
In addition, our sales team has sent you a 1-month free license of Spire.XLS to help remove the warning message and better evaluate our product. Please refer to the following guide to apply the license.

Hi,

I use Spire.XLS Pack(Hotfix) Version:8.11.6 and there is really no a red line in DonutChart's.

But if I want to remove the warning message, do I have to buy your product after one month?

Thanks!

Dear Chen Ricky,

Thank you for your feedback.
Yes, you need to purchase our product if you would like to remove the warning message after the temporary license expired.
