Hello,
Thanks for your inquiry.
I simulated an excel file with a chart and did an initial test with the latest
Spire.XLS Pack(Hotfix) Version:11.4.6, but I did not reproduce your issue. If you are using an older version, please download the latest version and try it again.
If there are still any issues, to help us investigate further, please provide us with your input file. You can upload your file here or send it to us (
support@e-iceblue.com) via email. Thanks in advance.
Sincerely,
Brian
